    |
    +-Start Queue
    |
    |
    | <-- Exchange
   /|\\
  / | \

You need to implement this: http://www.eaipatterns.com/Aggregator.html but the RabbitMQBundle for Symfony doesn't support that so you would have to use the underlying php-amqplib.

A normal consumer callback from the bundle will get an AMQPMessage. From there you can access the channel and manually publish to whatever exchanges comes next in your "pipes and filters" implementation
