From the minimal research I've done looking for a decent client I doscovered that:
E-Donkey was originally a great source for programs and beta release programs such as Windows XP but now video seems to be the file de jour. The downside to this program is that it apparently has some security issues, there's already been a publically available buffer overflow exploit available for older versions. To the developers credit, it was fixed pretty fast.
Kazaa is pretty much the artist formally known as Morpheus. This software has integrated spyware built-in. Be warned that
Kazaa Lite still has spyware integrated !!! (If anyone wants a version of kazaa that has no spyware PM me.
kazaa or edonkey? hell I use both, if I can't find it on one I use the other
WinMX and Grokser are the only two p2p clients that come close and they kinda suck.
