That's not defined in the spec. In fact, a jms server doesn't even have to support
two receivers on the same queue.

What you are doing won't work anyway unless the messages are
non-persistent. The "noLocal" is a check for is it the same connection,
NOT is the same client computer.

WIth an MDB (or any other receiver of persistent messages) it can reconnect 
(e.g. due to a failure) and the "noLocal" won't work because it is no longer the
same connection.

Only to put a property in the message and use a selector to say I don't
want messages where the property equals the one that I'm setting in my sends.
But then you have to think about how you persist that value across failures.

Basically a more durable version of "noLocal".
