python marienz@gentoo.org Vertex is an implementation of the Q2Q protocol (sort of like P2P, but one better). There are a few moving parts in Vertex: PTCP is a protocol which is nearly identical to TCP, but which runs over UDP. This lets Q2Q penetrate most NAT configurations. JUICE ([JU]ice [I]s [C]oncurrent [E]vents) is a very simple but immensely flexible protocol which forms the basis of the high-level aspects of Q2Q. vertex is a command line tool which exposes a few features useful in many situations (such as registration and authentication).
