Hi Rob,
Thanks, that's good to know.

Let's say I change the example to using machine hostnames or IP 
addresses. In that case there are not going to be large numbers of 
unique names in use at any one time, but over time the names may stop 
being used and new ones will appear.

So I could use STOMP destinations such as:
/queue/hostname.foobar.example.com

Is there a way to clean up the queues once those machines have gone 
away, say after some months or more of use?

I couldn't spot anything on the STOMP plugin page, nor the rabbitmq 
admin guide page.

I can see there is a "list_queues" option to rabbitmqctl, but not a 
corresponding delete_queue option.. Where would I find that?

Sorry about all these newbie questions..
Thanks again for your help,
Toby
