Thinking about this a little more, I really would not want to lose the
ability to do topic publishing in MQTT.  Fortunately, it seems there's
another way.  With Rabbit's Exchange-to-Exchange bindings (
http://www.rabbitmq.com/blog/2010/10/19/exchange-to-exchange-bindings/), it
seems that MQTT messages could first go to a topic exchange, and then based
on exchange-to-exchange bindings, be routed to a custom exchange (such as
the random one above).

Any reason this wouldn't work?  Am I really off in the weeds?
