Exactly what I need.

How does queue federation consumes from the queue? I mean it's not just
a normal consumer, because if nobody is on the other side, it won't
consume. Or it just starts consuming if there are somebody?
But there are even more conditions need to be true to get messages to it
(described on the federation page), so this is not so simple.
Also, if consumer A on broker A consumes from the queue, but broker B
can't consume from broker A's queue, I assume consumer B on broker B
will be able to consume from the queue on broker B, so this essentially
doesn't work in a federated setup.
Or is there something which disallows this?
