Hamachi

Hamachi is a UDP-based virtual private networking system. Its peers utilize the help of a third node called a mediation server to locate each other and to bootstrap the connection between them. The connection itself is direct and once it is established no traffic flows through our servers.

Hamachi is not just truly peer-to-peer; it is verifiably secure peer-to-peer.
