You mean interoperate on the wire protocol level, ie. instance of myLib 
directly communicating with instance of libzmq?

If so, it's pretty hard, but if you want to go that way it's probably 
easier to make in-house lib speak 0mq protocol rather then vice versa. 
The reason being that 0mq protocol is pretty simple, while in-house 
protocol is not likely to be.

Some other options are:

1. Bridge to convert 0mq messages to myLib messages and other way round.

2. Be compatible on the API level. Wrap libzmq in such a way as to 
expose myLib API.
