1. SSL runs on top of TCP, yet Twisted has connectSSL/listenSSL and
endpoints for it. So the issue here is not the fact it runs over TCP.

2. I assume ZeroMQ "Sockets" have capabilities TCP doesn't, otherwise
what's the point? :) E.g. you mentioned pub/sub. So, assuming a ZeroMQ
endpoint and/or listen+connect methods, the *protocol* you would pass in
would be different than the standard protocols you'd use with TCP or
SSL, yes?

So, sounds like you want to define:
A) A way to hook up ZeroMQ event loop with Twisted event loop so that
both ZeroMQ and Twisted code can co-exist in same thread.

Then, expose ZeroMQ APIs to Python in a way that gives you:
B) A protocol class or interface.
C) An API for creating and hooking up these protocols to underlying
transports, i.e. ZeroMQ Sockets.

You could then release this as txZeroMQ; I'm not sure there's much
benefit in including this in Twisted, as opposed to standalone project.
