I'm from Awcloud, an IaaS provider in China. We built our OpenStack 
clouds based on ZeroMQ in multiple DCs during this year.

As I stated in the last thread, we've contributed several patches. The 
last one to make it work is reworked now.

AFAIK, ZeroMQ is non-AMQP low-level communication method, so there are 
some gaps which cannot be ignored, how it works, how the nodes 
communicate with each other via ZeroMQ driver, how to make it run, how 
to debug, any tuning methods for production, etc. Actually, it seems 
that every aspect is totally different from AMQP-based methods, like 
qpid or rabbitmq. Everything needs to be documented to guide people who 
are interested in this driver.

I just noticed that dropping ZeroMQ is on the plan:

Damnit, I lost previous discussions on this topic. I'm mainly working in 
other projects in most of the time. Right now, I'm willing to contribute 
from now on. My colleagues are also available to help.

Yes, it's great that someone is working on that way.

ZeroMQ driver test cases are developing.

I'm not sure the progress, but I can try to link him and see if we can 
work together to get it done. Meanwhile, I'll start to investigate other 
must-do. OK, actually I'm not very clear about the priorities of 
must-do. So, Doug, what do you think of it?
