Here is the position paper that accompanied the talk: "Experiences Deploying a Large Scale Emergent Network" http://www.cs.rice.edu/Conferences/IPTPS02/188.pdf While speaking in front of this small audience of eminent systems researchers, and while answering their questions, I realized that a simple hack should make a big difference in the overall reliability of the file space: do not publish data to a server unless you have seen that server before, more than one hour ago! And more generally, use the age and average availability of a server as a general heuristic for preferring to publish to him. This was idea was inspired by a DHT ("distributed hash table") design named "Kademlia" that I really like: [2]. See my paper to understand why this heuristic would make such a big difference. It is easy to implement something like this using a handicapper, and I intend to do it for the next Mnet release.
