aMule
aMule is an eMule-like client for the eD2k and Kademlia networks, supporting multiple platforms.
Currently aMule (officially) supports a wide variety of platforms and operating systems, being compatible with more than 60 different hardware+OS configurations.
aMule is entirely free, its sourcecode released under the GPL just like eMule, and includes no adware or spyware as is often found in proprietary P2P applications.
