Just a comment on the 'speed' of different versions of kazaa...
No version is going to get you a significant speed increase. It's the users you're downloading from that counts. Sure, the newer K-Lite's have download accelerators that keep finding more users, but that's no good if there aren't enough users to get the file from with good connections. The reason you get different speeds among different versions is purely coincidental, it all depends on what users are on and what their connection is.
And yes, I too seem to be disconnecting/reconnecting more than usual...hmm....maybe the Sharman network finally caught on to K-lite?
Personally, I think the whole 'blocking RIAA IP address' thing is crap. They can only detect the RIAA's IP after the RIAA has already done something with it, so if you're the first person to get hit by them, then you're screwed anyway. It's too easy to change IP's for the IP blocker to work effectively. The 'disable sharing of files' thing is the only way to go, but some K-Lite users will automatically cancel your download if they see you not sharing files.
