The Circle. The Circle is a scalable decentralized peer to peer application. Which is quite a mouthful. In English, what this means is that there's no central authority running the show. Which means no entry taxes, no one booting you off the network, and (in theory) no weak point which can break the whole system. As long is there's one Circle peer running, anywhere in the world, there's still a network. Circle does not try to provide anonymity, which allows it to be much more scalable than gnutella.
