With regards to the general Virtual Topics use case. We're making some
improvements to the Artemis addressing model. See
https://issues.apache.org/jira/browse/ARTEMIS-780. I think these changes might
make it easier to use equivilent "shared topic" behaviour.
It will depend on the protocol you are using as to how this would behave.
But, you should be able to either get direct access to a pre-configured queue
and add another consumer on it. The abilty to reference queues directly is
something we'll be exposing.
Alternatively, you'll be able to subscribe to the same "durable"
subscription as another client, by using the same client id (again protocol
specific here). For AMQP this would be the container-id, for JMS and STOMP
client id.
