I fear your question is too specific (which means you must investigate
yourself).

First of all, it is always very difficult to answer questions
like "the best way" -- many many details are involved there.

You provided details but to appreciate them one has to know
"AMQP", "Openstack Notifications", "twisted", "greenlets", ...
There will not be a lot of people with this knowledge (I do not
belong to them).


I believe that you will be able to realize a solution
based on (Python) threads. It gives you the more freedom
than "twisted" or "greenlets". But a different approach
might be "better" (in some respect).
