    @michaelandrepearce to make the feature work is trivial in queueimpl; to make it dynamic is a lot of code.
    I would have been shooting for an address setting and pulling that value in queueImpl on creation. An all or nothing approach.
    But what you have is very comprehensive :-) I just wonder if there really is a need to have the consumer create an lvq or exclusive queue. If there is, then this nails it.
    For an existing openwire client the value can come from a consumer info or from a destination parameter but mostly it is the effect that is needed, not the fact that it is dynamic, ie: Because it effects every consumer having a single consumer control it is a bit imbalanced and not typical I think.

> Artemis should support a consumer feature where a single consumer receives all messages, even when multiple consumers are present. This capability maintains message ordering while allowing a HA consumer.
> ActiveMQ 5.x supports this, as does IBM MQ, Tibco EMS, etc.
