MLdonkey is a multi-platform multi-network peer-to-peer client. It supports several large networks, such as eDonkey, Overnet , Bittorrent , Gnutella (Bearshare, Limewire, etc), Gnutella2 (Shareaza), Fasttrack (Kazaa, Imesh, Grobster), Soulseek, Direct-Connect, and Opennap. Networks can be enabled/disabled, searches are performed in parallel on all enabled networks, but each file is only downloaded from one network, but from multiple clients concurrently.
