I'm not sure I understand your question, but:

* Exchanges live on all nodes by definition
* Non-mirrored queues live on the node on which they were first declared
* Mirrored queues live on whichever nodes their mirroring policy implies
* Therefore declaring two non-mirrored queues on the same channel will 
put them on the same node
