File Sharing: Decentralizing, Open-Source Fasttrack

Eloquence writes: "I've written a comparison of current file sharing software; what's interesting is that the original centralized indexing concepts are losing ground because of filters, and most relevant file sharing systems by now use at least a server-network, or a completely decentralized architecture. Unfortunately, most networks are proprietary, but at least there is now an open-source client to access the most popular network, Fasttrack's Kazaa/Morpheus, which was originally only accessible under Windows (around 500,000 users online at any time)."
