I thought it was possible to create Topic hierarchies like topic/foo, topic/foo/bar, topic/foo/baz, etc. The point being to have a client listening on topic/foo so that he could hear all messages going to both topic/foo/bar and topic/foo/baz.
This isn't possible and you were misinformed
Damn! Oh well, thanks for the reply. Seems like a pretty logical thing to want to do though.
