The problem is, on the internet, nobody can hear you.

Today I realized what Q2Q is. It is a (I swear, this just came to me, I was not even trying to make it sound like anything) Self-Certifying Remote Endpoint Authentication Mechanism, or "SCREAM".

A SCREAM in this sense is a mechanism whereby connections are authenticated by cryptographic means; where the handshake includes information identifying the connector to an arbitrary level of precision (in Q2Q's case, via an SSL certificate, that the connection is authenticated with)

It is self-certifying because the connection itself identifies itself, via both an in-band nonce and by TLS. All security is transport security.

It refers to a remote endpoint which is the other end of a networked communication. It identifies not only the user, but their agent, and optionally the capabilities and permissions of their agent.

It is an authentication mechanism because you use it to prove that your connection is authentic.

Also, Vertex will blow a hole in your NAT device the size of a watermelon: no kidding. Vertex is the Divmod implementation of Q2Q. We really want Q2Q to become a standard so we are making a big deal out of the separation between product and protocol.

(I really feel like there are some uses for this thing that I've missed. I really hope I have enough time to work on it in the next 6 months to see something through to fruition: other, less focused, worse P2P and identity solutions are starting to get some traction, and it bothers me.)
