A filesharing program (ie P2P) that allows users to download various media files. You have to conncet to a server like Razorback to get on a network. It's based of eDonkey2000, but also includes more options, a source exchange, and the KAD (short for Kademelia) network. eMule has several MODs like NeoMule, eMule Plus, and a leecher MOD, Hardmule. eMule's users are known to provide real files most of the time, and it's hashing (copy protection) algorithm is different from Kazaa's where it can't be broken. Speeds are much slower than any other p2p, there are many more users, and it's community seems to have more in mind than porn and mp3s like large rival Kazaa.
