N2N peer-to-peer virtual private network system.
N2N is a peer-to-peer virtual private network system. N2N uses the universal
TUNTAP interface to create TAP network interfaces to an encrypted virtual
LAN. Members of a community share a common encryption key which allows echange
of data. The supernode is used for peer discovery and initial packet relay
before direct peer-to-peer exchange is established.
Once direct packet exchange is established, the supernode is not required.
