I believe the OP's question pertains to the use of QueuingConsumer in 
this context. In particular, when using the same QueuingConsumer 
instance to consume from multiple queues, there is no way to distinguish 
which messages were delivered from which queues.

This could be addressed by adding the consumer tag to 
QueuingConsumer.Delivery. I have filed a bug for that.
