Thanks Michael & MinRK! That's exactly what I was looking for - I knew there has to be some simple way to do it. Now the only problem is one needs to have the zmq includes when importing stuff from libzmq. Is there a chance that these could be bundled with pyzmq when using a bundled libzmq instance? Otherwise 3rd party extensions will still require the zmq headers to be made available manually..
