hmm, d/l'ed 2.0 for OSX today and at first it was working wonderfully. Much faster, more responsive than the 1.8 it replaced. I seemed to get more hits and everything was d/l'ing very fast compared to the usual dinky speeds of 1.8 (I have cable modem also!). I closed the program and when I went back to it a few hours later to d/l again I had all the problems that all of you are complaining about. No hits. Needless to say I will be back in 1.8 for a while, but I think ultrapeer (at least the idea of it) seems very promising.
