The 7th International Workshop on Peer-to-Peer Systems (IPTPS '08) provides a forum for researchers to engage in a lively discussion of current and future trends in peer-to-peer systems, broadly defined. The workshop, to be held in Tampa Bay, Florida, provides a venue to present and discuss peer-to-peer technologies, applications, and systems, and to identify key research issues and challenges that lie ahead.

In the context of this year's workshop, peer-to-peer systems are defined to be systems that enable sharing and cooperation among ordinary users whether the underlying technology is decentralized or not. As a venue for exploring new directions, IPTPS takes the broad view that peer-to-peer systems are systems that enable mass collaboration, including but not limited to Internet systems, Web-based systems, overlay networks, online games, mobile systems, and online social networks. We encourage submissions of early work, with novel and interesting ideas. We expect that work introduced at IPTPS 2008, once fully thought through, completed, and described in a finished form, may be relevant to conferences such as NSDI, OSDI, SOSP, Sigcomm, Sigmetrics, Usenix, Sigmod, VLDB, Mobisys, Mobicom, PODC, or SPAA. Topics of interest include, but are not limited to:

* Networks and systems support for peer-to-peer systems
* New applications and protocols for peer-to-peer systems
* Availability, robustness, performance, and scaling
* Security, privacy, anonymity, and anti-censorship
* Attack resistance, policy enforcement, and participation incentives
* Lessons drawn from experience with deployed peer-to-peer systems

Papers will be selected based on originality, likelihood of spawning insightful discussion and technical merit. The program will include presentations of position papers along with plenty of time for lively discussion among the participants. To ensure a productive workshop environment, attendance at IPTPS will be limited to 60 participants. Invitations to attend the workshop will be extended according to the following priorities:

* the Program and Steering Committees, one author per paper, and any speakers invited by the Program Committee
* co-authors of accepted and submitted papers
* event-sponsor representatives and additional authors of submitted papers at the discretion of the Program Committee

Submission Guidelines
Authors may choose to submit a blind or non-blind paper. A blind submission will not indicate the names or affiliations of the authors in the paper; a non-blind submission will include the names and affiliations of each author on the first page of the paper. Please do not submit abbreviated versions of journal or conference papers. In particular, submissions to IPTPS must not be concurrent with a substantially similar submission to a conference, including condensed versions of work that has been submitted to a conference and is currently under review. Papers should follow these guidelines:

* 6 or fewer pages, including appendices and references
* One or two columns
* Font size must be no smaller than 11pt
* Pages should be numbered
* Only PDF or PostScript formats will be accepted

Accepted workshop papers will be archived electronically, but there will be no formal published proceedings of the workshop. Accepted papers may be subsequently revised, expanded, and submitted to full conferences and journals.
