PyZMQ already hides the difference between libzmq-2.1 and libzmq-3.1, so
IPython does not have to worry about that difference at all.  At this
point, libxs *is* libzmq-3.1, and pyzmq should work perfectly well with
libxs as long as it is built with its libzmq-compatibility flag (which
simply restores original names of things).  For the near future, pyzmq will
rely on the Crossroads libzmq-compatibility.  We will see how libxs
develops and diverges from libzmq, and how that affects what is needed to
support both (and how the zmq community moves with respect to the fork as

Essentially, all of this compatibility will happen in pyzmq itself, and
IPython should never need to be aware of any of it.
