Kademlia
From AMule Project FAQ
Kademlia is a serverless network for the *Mule clients.
It is based on the Kademlia algorithm by Petar Maymounkov and David Mazières (New York University, 2002).
It is not a completely independent network as many people think. It still uses the eD2k network, but provides a server-less way to find other clients and files.
For information about it you can either read the ED2K-Kademlia FAQ or see eMule's support page.
