The part you are missing is the piece that "connects" the queue on Exchange A to Exchange B. Prior to the upcoming 1.0 spec, AMQP does not define anything special for broker-to-broker mechanics.
You might consider the rabbitmq-shovel plugin to "shovel" the messages from one broker/exchange to another. In your case, it would be from a broker in geographic location A to an analogous broker in geographic location B.
With shovel, the flow would look more like this:
[ ......... Broker A .......... ] [ ..... Broker B ..... ]
App B --> Exchange A --> Queue A --> Shovel -+WAN+-> Exchange B --> Queue --> App B
I hope this helps!
