Yes. It's doable. You are right, zmq_init_t is the right place do it.

The only problem is that it breaks the wire-level interop.

Inproc is different from other transports in quite a few respects. As 
for the type checking, there's an inproc registry inside ctx_t. Now it's 
just a map from endpoint name to socket pointer. It should be enhanced 
to hold the socket type as well, so that the connecting party knows what 
socket it is connecting to.
