I can help with that; my team spent some time last week sprinting on
ZeroMQ support in Oslo Messaging/OpenStack to assess its potential for
scale and current state so I think we've already answered quite a few
of those questions, as well as started work on getting unit and
functional tests up and running for the ZMQ driver.

We also managed to persuade Pieter Hintjens (ZeroMQ upstream) to pop
by and review the overall design of ZMQ driver - he gave it a general
+1 and we have a list of longer term improvements to make.

Li - I'll ping you directly to co-ordinate on this activity next week
and then we can come back to list to report the details.

The scale potential is very appealing and is something I want to test
- - hopefully in the next month or so.

Canonical are interested in helping to maintain this driver and
hopefully we help address any critical issues prior to Juno release.
