I gave a talk about my experiences with Mojo Nation at the First International
Workshop on Peer-to-Peer Systems [1] recently.  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big difference in the overall reliability of the file space:  do not publish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.

Regards,

Zooko
