Divmod Vertex is an implementation of Q2Q, a
protocol for opening authenticated connections,
even through NAT. It allows a user to reliably
demonstrate their identity (for distributed
authentication) and receive real-time data
directly from other users, and provides a
mechanism for a user to decide whether they want
to expose their IP address to a third party before
accepting a peer-to-peer connection. It is
byte-stream oriented and application-agnostic. Any
peer-to-peer application can use Q2Q to open
connections and deliver messages.
