That is definitely cool.  Perhaps we should provide a note in the message
doc that describes how to use custom serialization, and various useful
libraries such as this one.

Once the Session object in the parallel code replaces the one in IPython.zmq
(already done in a local branch, but waiting for newapp to merge), the
message serialization will be user configurable, just like it is in the
parallel code.  The message spec only requires that messages be JSONable
(simple dicts/lists of strings and numbers), and there is no code (or
shouldn't be, anyway) outside the Session that deals with JSON directly.
