I found this recently and thought I'd spread the word. This is made by the same people that brought us WinMX, and even has the famous traffic light connection indicator, but it's not compatible with the WinMX network. I gave it a try and it seems decent, not so many files on it so far, but that's to be expected for a newcomer.

Fopnu is far better than the rest:

Simple and easy to use
Fully decentralized network
All shared files are indexed locally
No relaying of other user's searches
Pure UDP protocol that utilizes forward error correction
Full connection encryption and decentralized public key infrastructure
Recirculating token system that helps distribute upload bandwidth fairly
Efficient and fast transfers via re-combining and re-encoding blocks at all nodes
Clean install and uninstall, or stand-alone operation, with no annoying .Net or Java dependencies
NO Spyware NO Ads NO Nonsense
