On a conceptual level, the message will always be routed to the master. 
On a practical level it will also go to all of the slaves (in case the 
master fails before seeing it) but the master will be the one in charge 
of enqueuing it.

It's best to view the queue as one distributed object, but if you need 
to find out the current master you can use rabbitmqctl or the management 
API.

No.
