Hmmm, the main "problem" would be that debugging will be awfully hard.

Other than that, there is no (reasonable) limitation on the number of contexts you create. The whole purpose of a zmq_context is to solve the library problem that you describe, so if it doesn't work then there is a fundamental problem with zeromq itself. :)
