What you actually need, apparently, is a zmq_device. I'm not sure how 
you do that in Python.

Again, I think this is another example for the case where it should be 
allowed to bind multiple times to an address over the same context, so 
that multiple threads can service a single port, e.g.

ctx = zmq.Context(1)
workers = []

def createThreads(numThreads, endpoint):
     global ctx, workers
     for i in range(0, numThreads):
         sock = ctx.socket(zmq.REP)
         thread = new Extended_thread(sock)

You can do this with a device, but if you're going to be doing it all 
over a single context, it just seems like so much cpu wastage :)
