Indeed, we'll do our best to help out here so that the discussions
also can get the input from others are searchable in the archives,
etc.

Does this make sense to you guys?

Brian, should we move the message spec from the pyzmq toy example into
IPython itself?  Ondrej and Mateusz were today in town for a
py4science meeting and we went together over the message protocol and
demo. They've been building a very neat web frontend, and it would be
good to start standardizing the protocol properly in IPython beyond
the little zmq experiment.  Are you OK with moving this over?

Cheers,
