If you're looking for the latest and greatest P2P file sharing option, look no further than Shareaza.
It pulls from 4 networks: EDonkey, Gnutella, Bittorrent, and Shareaza's own network, Gnutella2. So the odds are higher than ever that you'll find what you seek! Shareaza has a built-in media player and zero popups. Cool graphics on torrents, too. Give it a whirl and let me know what you think.
