Peer-to-Peer (P2P) networks enable users to directly share digital content (such as audio, video, and text files) as well as real-time data (such as telephony traffic) with other users without depending on a central server. Although originally popularized by unlicensed online music services such as Napster, P2P networking has recently emerged as a viable multimillion dollar business model for the distribution of academic and clinical information, telecommunications, and social networking. Written at an accessible level for any reader familiar with fundamental Internet protocols, Peer-to-Peer Networking and Applications explains the conceptual operations and architecture underlying basic P2P systems using well-known commercial systems as models. The book also delineates the latest research directions, thereby providing not only a sophisticated understanding of current systems, but also the means to improve upon these systems with innovations that will better performance, security, and flexibility. Peer-to-Peer Networking and Applications is thus both a valuable starting point and an important reference to those practioners employed by any of the 200 companies with approximately $400 million invested in this new and lucrative technology.
* Uses well-known commercial P2P systems as models, thus demonstrating real-world applicability.
* Discusses how current research trends in wireless networking, high-def content, DRM, etc. will intersect with P2P, allowing readers to account for future developments in their designs.
* Provides online access to the Overlay Weaver P2P emulator, an open source tool that supports a number of peer-to-peer applications with which readers can practice.

EDIT:
Stealth P2P network hides inside Kazaa
A California company has quietly attached its software to millions of downloads of the popular Kazaa file-trading program and plans to remotely "turn on" people's PCs, welding them into a new network of its own.
Brilliant Digital Entertainment, a California-based digital advertising technology company, has been distributing its 3D ad technology along with the Kazaa software since late last fall. But in a federal securities filing Monday, the company revealed it also has been installing more ambitious technology that could turn every computer running Kazaa into a node in a new network controlled by Brilliant Digital.
The company plans to wake up the millions of computers that have installed its software in as soon as four weeks. It plans to use the machines--with their owners' permission--to host and distribute other companies' content, such as advertising or music. Alternatively, it might borrow people's unused processing power to help with other companies' complicated computing tasks.
Brilliant Digital CEO Kevin Bermeister says computers or Internet connections won't be used without their owners' permission. But the company will nevertheless have access to millions of computers at once, almost as easily as turning on a light switch.
"Everybody will get turned on in more or less a simultaneous fashion," Bermeister said. "This will be an opt-in program...We're trying to create a secure network based on end-user relationships."
The Brilliant Digital plan is the most ambitious yet from a string of companies that have tried to make money off the millions of people who are downloading and using free file-swapping programs such as Kazaa, MusicCity's Morpheus or LimeWire.
Nearly all of the file-swapping programs now routinely come bundled with so-called adware or spyware--programs that automatically pop up advertisements while people surf the Web or that keep track of where someone surfs, information that can then be sold to marketing companies. Despite growing concerns about this bundled software, usage and downloads of the file-swapping programs are at an all-time high.
But Brilliant's plan, by tapping into the computer resources of the file-swappers themselves, has fallen into a new realm where start-ups such as Kontiki and Red Swoosh are just starting to gain traction. Those companies are trying to use peer-to-peer technology to distribute content more quickly online, but they face a battle convincing people to install their software and become distribution points.
Brilliant, by contrast, already has potentially tens of millions of computers in its network, simply by piggybacking on top of Kazaa.
According to CNET Download com, a popular software aggregation site owned by News.com publisher CNET Networks, the Kazaa software--and by extension the Brilliant software--was downloaded more than 2.6 million times last week alone. Brilliant has been distributing the core technology for its peer-to-peer service along with Kazaa since February, Bermeister said.
Brilliant Digital's federal securities filing The Brilliant network is based on a piece of software called "Altnet Secureinstall," which is bundled with the Kazaa software. That technology can connect to other peer-to-peer networks, ad servers or file servers independently of the Kazaa software and can be automatically updated to add new features, according to Brilliant's filing.
When the software is "turned on," computers running the Brilliant software will form a new peer-to-peer network separate from but connected to Kazaa, the filing said. A few computers with fast connections will form the early core of the network and be asked to join first. Other ordinary computers and Net connections will be invited later, Bermeister said.
Brilliant's software will be able to understand and respond to searches inside Kazaa, since it is based on the same technology. But if it is successful, Brilliant will be able to host content and run "distributed computing" applications over the new network that is entirely separate from Kazaa or other file-swapping networks based on the same technology.
Working behind the scenes
Brilliant and Bermeister have played a central role in many of the events shaping the file-swapping world in the past few months.
Bermeister began distributing his company's 3D advertising software along with the Kazaa software last year. That's how he got to know the founders of Kazaa BV, the Dutch company that created the file-swapping technology originally used by Kazaa, Morpheus and Grokster.
When the Kazaa BV founders decided they didn't want to be in the network business, Bermeister introduced them to a former associate in Australia, Nicola Hemming. Her new company, Sharman Networks, bought the Kazaa software and continues to distribute it.
Bermeister is now drawing on his association with the Dutch programmers for his new venture. Brilliant has created a new company for the peer-to-peer service, called Altnet. It has licensed the Dutch programmers' technology from their new venture, called Blastoise. According to Brilliant's annual report, filed Monday, the Dutch programmers have taken a 49 percent stake in Altnet.
Brilliant has been subpoenaed in the record labels and big movie studios' copyright infringement lawsuit against Kazaa BV. No suit has been filed against Brilliant or Sharman Networks, however.
The immediate plans for Altnet, Brilliant and the new peer-to-peer network remain unclear.
Bermeister said the company had been testing the technology along with ad giants DoubleClick as a way to serve ordinary Web ads more quickly. Under this plan, an ad that a person sees on a Web site might be hosted by a nearby computer running Brilliant's Altnet instead of on a central ad server, as now typically happens with DoubleClick.
Brilliant's CEO was quick to note that people would be asked before their computers were used for this or other purposes. He said the software would show a pop-up box explaining the network's function and giving people a chance to turn it off. People who allow their computers to be used will be compensated somehow, possibly with gift certificates or free videos, the company's filing said.
However, people who accept "terms of service" already distributed with Brilliant's and Kazaa's software are already agreeing to let their computers be used without any payment at all.
"You hereby grant (Brilliant) the right to access and use the unused computing power and storage space on your computer/s and/or Internet access or bandwidth for the aggregation of content and use in distributed computing," the terms of service read. "The user acknowledges and authorizes this use without the right of compensation."
How to uninstall Brilliant Digital's software Anybody who declines this provision is not able to install the Kazaa file-swapping software. Brilliant's software can be disabled or removed after installation without affecting Kazaa's performance, however.
A representative for Sharman, which distributes the Kazaa software, could not be reached for comment.
Privacy-rights advocates contacted for comment expressed some concern about the way the Altnet software has been distributed and about whether the millions of people who already have it installed on their computers will be tech-savvy enough to know what they're agreeing to when and if Brilliant does ask to use their computers.
"A lot of the people most likely to use this software are teenagers or college students. There's a lack of sensitivity about privacy in that age group," said Larry Poneman, CEO of Privacy Council, which helps companies manage privacy issues. "
o they really want to be commandeered and have their machines do things that aren't necessarily in their best interest?"

LimeWire bites back in P2P war
By Jim Welte - MP3.com
September 26, 2006 at 11:52:00 AM
Unlike most of its P2P counterparts, file-sharing service files a countersuit against the music industry, alleging anticompetitive practices and consumer fraud.
In the 15 months since the US Supreme Court's landmark decision on peer-to-peer file sharing, most of the major P2P outfits have either paid settlements to the RIAA and folded or gone legit.
All but two, that is.
While Morpheus operator Streamcast, one of the named defendants in that landmark case, continues its legal battle with the music industry, another P2P giant is fighting back.
LimeWire, sued by the major record labels last month for copyright infringement, filed a countersuit yesterday in US District Court in New York, alleging antitrust violations, consumer fraud, and anticompetitive practices.
In the complaint, LimeWire doesn't address the copyright infringement claims against it. Instead, the suit argues that the major record labels "have unreasonably and concertedly refused to do business with LimeWire," in an attempt to "prevent the use of decentralized peer-to-peer technology for the secure distribution of licensed, copyrighted content."
The complaint based its anticompetitive practices charges on digital music ventures that the major labels have or have had stakes in, such as digital retail platform maker MusicNet and failed online retailer pressplay, which eventually became the latest version of Napster.
The countersuit also points to the labels' relationship with Mashboxx and iMesh, two of the formerly illegal P2P firms that have since launched industry-supported legal versions. The claim says that P2P firms seeking to go legit have been forced to adopt the model used by iMesh, which uses acoustic fingerprinting technology developed by Audible Magic to police its networks of illegal files.
"The [labels] have concertedly promoted the distribution of licensed content through companies in which many of the [labels] and business affiliates have or had direct equity interests, such as MusicNet, pressplay, and Roxio, or through business entities that they have a relationship with, such as iMesh or Mashboxx," the counterclaim reads.
"This case is but one part of a much larger modern conspiracy to destroy all innovation that content owners cannot control and that disrupts their historic business models," the counterclaim alleges.

The death of P2P
Last week, prominent P2P network eDonkey announced it was settling a copyright-infringement lawsuit brought by the Recording Industry Association of America for $300 million and closing up shop forever. Users who clicked a button to update their eDonkey2000 software reported the "update" initiated an uninstallation of the product. Visitors to the eDonkey Web site are now greeted by an intentionally blunt message advising surfers they are not anonymous online (and playfully proving it by displaying visitor IP addresses).
Only a month ago, we learned that former top file-sharing program Kazaa settled with the RIAA for $115 million, and that current top P2P application LimeWire was being sued for an estimated $476 million. The LimeWire case is expected to go to court next month.
The demise of the original Napster file-sharing program marked an immediate rise in decentralized peer-to-peer networks. Now it seems that U.S. copyright law and other influences are causing file sharers to drift toward the non-node-connected BitTorrent protocol, which allows users to download one file from multiple sources simultaneously. The legality of various BitTorrent software and "tracker" sites is still undecided, but a recent partnership between Warner Bros. and BitTorrent indicates the technology is integrating with mainstream Hollywood.
It appears as if the one-two punch of suing individual file-sharers and the companies that develop peer-to-peer technology may have ended the long reign of conventional P2P networks

P2P scam site settles with FTC
30 May 2006 12:42 by Dela
A man who was advertising subscription to his site as a way of downloading music without having to face litigation has reached a settlement with the Federal Trade Commission (FTC). Los Angeles man Cashier Myricks settled the deception charges brought against him after the FTC alleged his site deceived users into thinking that his referral or tutorial conferred a license to share copyrighted files. Mp3downloadcity.com contained nothing more than tutorials to use free P2P software.
Myricks was charging $24.95 for access to his tutorial which he claimed would make file sharing "100 per cent legal". The FTC filed the suit against Myricks in September 2005 and the settlement now brings an end to the legal action. As part of the settlement, Myricks must return the more than $15k the FTC alleged he received to 611 individuals he had duped into forking out the cash.
From now on he must also inform users that "using P2P programs to download copyrighted music, movies, games, or other material without a license from the copyright holder can subject you to lawsuits, fines, and even criminal prosecution." He is barred from making future misrepresentations about the legality of any computer product also.
The Internet is full of similar sites that claim users will be able to download 1000's of movies and games and millions of MP3s for either a once of payment, or sometimes even a subscription fee. Many of these sites often turn out to either contain guides to using P2P services, to using Newsgroups (and might also provide a low quality news server) or a list of public FTP sites gotten from IRC channels and/or public/private BitTorrent trackers.
