An experiment in making a CMS based on P2P technology. A good article, scientific. Several good points. Pretty technical.
The obvious benefit of having a distributed repository is scalability, but it is suggested that content ownership/quality is increased since the content is local.
The authors make a point of using open standards, though not a very good one (java and XML). JXTA is one of the more exciting and relevant standards.
The experimental implementation of the system had not been completed at the time of writing, and I can't find any continued effort on the net. Bit of a shame actually, sounded like a very reasonable implementation. A good idea and a good architecture, but I guess our centralized servers are still strong enough for handling all content.
