Vertex (currently available at <http://bazaar.launchpad.net/~divmod-dev/divmod.org/trunk/files/head:/Vertex/>) implements peer-to-peer communications and NAT traversal in Twisted, and has been seeing some fresh maintenance lately. There's too many moving parts and confusing details about how it accomplishes its task to go over in one email, but hopefully some of the folks who have been working on it lately can help you out :).
