So generally this involves replying to the 'reply-to' destination
which is described here...

http://stomp.codehaus.org/Stomp+JMS

when sending a message to a queue, if you want a reply, set the
reply-to header to point to the queue you will use to process replies.

The one thing thats missing right now is an easy Stomp way to create
temporary queues (in JMS-speak) for transient reply-to queues that
last the duration of your client. For now just use a queue per client.
