SENDing a message to destination "a" is performing a basic.publish to 
the default exchange with a routing_key of "a". So in order to receive 
the message in AMQP-land you need to declare a queue named "a".

For more complex routing topologies the SEND needs to carry an 
'exchange' header, which then allows you to use any exchange of any 
type, and bind queues to that exchange in the normal AMQP way.
