True. However:

You cannot change the namespace of 0MQ/1.0 because that would break 
existing applications.

You can change namespace of 0MQ/2.0, but then the question is how? 
Functions like zmq2_msg_init, zmq2_recv, ZMQ2_PUB etc. would be plain 
ugly, zeromq_msg_init, zeromq_recv, ZEROMQ_PUB etc. on the other hand 
are too long to be convenient.
