brian, peter

	for what its worth, i have changed jobs and am now full-time developing Go
code using zeromq. in my last batch of zeromq code, i had switched from “plain”
zeromq to using czmq, and found that process quite satisfying. using the
improved (to my mind) API, and the various classes, simply made my code
smaller and easier to do.

	so i will be a willing guinea pig for go czmq, and should that not work out, then
i would happily drop back to zmq4.

I have some problems that I am working on solving at work, so I've got some real world issues I'm exploring.  I don't really have a set "plan" yet - things that I find that are useful to me, I'll add.  Things other people send as pull requests that are useful, I accept.  I anticipate that I'll experiment a lot and have some false starts - it's a learning experience.
> I'll second what Pieter suggested - consider moving the bindings into the zeromq org, and try out the C4 process as a way to allow for low friction contributions.  We seem to have gathered together a small group of people with an interest in both go and zeromq at this point - with some cross pollination of ideas I bet we can have some fun and build some useful things!
