P2P Software for the Mac?

NeptalTim asks: "I've recently started using the Mac as my primary computer again after a hiatus of several years. All 'switch' jokes aside, I'm liking it very much, except for the decided lack of good P2P software. I always used Kazaa on Windows, but the best app I've found for the Mac is Limewire, which is a tad slow to say the least. What do Slashdot readers in the Mac community use for P2P?" I've been using iSwipe for a short amount of time and have found it useful. It's no WinMX, but it works. What other P2P programs have you found that you like?
