It's a plausible use case but what I would do, when making a
performance-critical binary protocol, is use a hand-tuned codec class
that used the libzmq API directly. For one thing you want the
constants to be invisible to applications anyhow.

We did this in FileMQ and Zyre and it creates nice classes that use
the same CLASS style as CZMQ.

Then we can ask the question of whether we can improve the zero-copy
API and performance in libzmq.
