ok then,
i will keep on looking for those statistics, but in the meanwhile would you guys care to brain storm a bit?

would should i look for when trying to simulate a p2p environment?

i guess i should use ping messages to find out if my neighbors are still around and record that, as well as the time each servent was in my cache and the number of messages each peer sent through me, but how can i check for message failure, how can i decide whether i received no reply to my query due to servent failure, congestion, lack of information etc.

any ideas?
