Can anyone point me to an uncomplicated Mac p2p? (ppc, universal) 10.4

I have Limewire right now, but the network seems very limited and it's difficult to find anything that isn't mainstream.

Bittorrent is good and all, but not for small, individual files.

I recently DL'd Shakespeer and Valknut, but I can't make any sense of either of them.

Is there anything out there that is as simple to use as Limewire, but with a better network?

I'd also like to ask that any piracy drama be left at the door.. mostly I search for independent, free releases.
