Libzmq does not do regular expression matching. If you want this, it's
trivial to add in subscribers using a regexp library.

In 3.1 subscriptions are sent upstream to publishers.

Probably this week. We're closing one or two issues. But the libzmq
git master is already pretty stable, and it's what I'd develop a new
application on today.
