So it's not totally driven from the client side then?

I would say disconnect it and any further operations (e.g. receive()) on that consumer should throw an exception.

A non clustered destination is, by definition, non clustered. Therefore there is no expectation of HA for that destination.

That's cool.

I'd just be careful of going too far down the wrong path. Otherwise you may have a *lot* of refactoring to do :)
