Alliance takes the best from BitTorrent, Direct Connect and Waste and creates a decentralized and secure p2p network. It is a private and secure environment to share files and communicate with people you know. Alliance works on Windows, Linux and Mac.
This build is the version that works with my puppy 525 (I've tried 3 other versions that didn't work) :
