How to get the routing ID of a `PEER` socket?

[jbdyn]

I am trying to get PEER sockets to bind and connect to each other.
The docs say that a message must contain a routing ID, which should be retrieved with zmq_connect_peer.

However, I cannot find the corresponding function in pyzmq and connect does not hold the routing ID.

How can I get the routing ID for a PEER socket?

pyzmq doesn't yet expose the draft zmq_connect_peer and zmq_disconnect_peer methods, so I'm not sure if you can use these from pyzmq yet.
