In practice, other solutions exist. I'm not sure which one is

(1) With ActiveMQ, one can subscribe to /temp-queue/whatever and a
private queue with a random name will be created on the broker. The
client program can send a message to itself, examine the destination
header of the received message and find out this way what is the real
queue name.

(2) We could imagine using the RECEIPT frame to allow the broker to
"reply" to the client. Something like:

  SUBSCRIBE /i-want-a-private-queue


> SUBSCRIBE /reply/<md5 of some client properties>

This would work too.

For instance. AMQP 1.0 has nodes, queues, links and filters (and no more
exchanges). They should be exposed via STOMP somehow.

In addition, AMQP 1.0 introduced the notion of global addressing,
something like node-name at container. This should also be usable from

However, I'm not up-to-date with what AMQP 1.0 really is today. Concepts
like remote addressing have been described for instance in last year's
F2F meeting:
I don't know if these are still relevant...
