I wish there was some kind of way for us to issue push notifications to
the client, i.e., have the client register some sort of callback and
what piece of data / state change they're interested in, then nova would
call that callback when the condition occurred.  It probably wouldn't
stop polling, but we could ratchet down rate limits to encourage users
to use the callback mechanism.

Of course, then there's the problem of, what if the user is behind a
firewall or some sort of NAT... :/
