Apropos of this - I read
http://engineering.linkedin.com/distributed-systems/log-what-every-software-engineer-should-know-about-real-time-datas-unifying
with plenty of 'well yes' and 'great way to put it' moments - have you
considered that perhaps kafka (or a matching implementation in
Python/whatever) might make a great bridge between the mailbox needs
your current API offers, and the realtime delivery needs that
oslo.messaging serves.

I don't know if that would look like a different backend, or perhaps a
migration to just offering multi-tenant kafka, but I thought I'd ask
since I don't recall seeing it discussed :).

One reason in particular for me asking is that we have really only a
couple of experiments in pushing events cross-API-server today, and
they aren't super great answers. If we had a clear API that was
scalable and fast enough to replace both those cross-API use cases and
the plumbing use case, we might be able to simplify our stack
substantially - and that would pay off vs the new deployment overhead
of a new component.
