Yes, I mentioned federation but in this context shovel is pretty much the
same thing, although perhaps a little lighter than federation. Going down
the route of several brokers, indeed, I see it becoming a pain quite soon.

Perhaps some guys of the dev team can shed some light given their greater

I never used it personally, but if you're going to require a central store
anyway you may consider some messaging solutions that come with the storage
itself, after all according to what you describe you would be leveraging
just a very small part of what RabbitMQ provides. For instance MS SQL
Server ships with a built-in message broker, I don't know how it works but
it may be worth investigating, and I'm sure other storages provide that as
well. Some googling of "distributed work queues" may turn up something
interesting too.
