Those fileshare things you see in Kazaa ARE IMesh, in case you were wondering. They just don't mention anywhere on their site that they're using FastTrack and try to keep it secret. Why, I don't know.
I tried Imesh today... what a load of crap... I ran Adaware just before I installed it and had Zero (0) hits -- ran the install and ran Adaware again... 35+ hits... guess what I did next... that's right Uninstall - and purged again with Adaware... I don't need it bad enough to have all the CRAPware installed on my system..
most important factor is the user, not the software. if there were too many leechers in the system the best p2p software will die.
if you want p2p survive, just share !!
