It seems like P2P developers don’t want to miss out on all the BitTorrent goodness. However, I’m pretty sure that existing BitTorrent users won’t switch to Ares too easily, but it’s a great opportunity for Ares users to discover the wonderful world of BitTorrent.
Ares uses the “Ares network” and is a free and open source Windows application. You can download the latest Ares version here.
