This sort of question is kind of answered in the AMQP specification
document. Might be worth taking a look at that for the background.

I guess your asking about what other MOMs call topics.

AMQP allows you to control how messages end up those queues. So by
specifying routing rules to multiple queues you can multicast each
inbound message to all of your queues.
