That would be really cool Jonathan. The major reason i fear to take the multiple subscriptions route is due to fears of performance degradation. If i can make do with a single subscription, which performs better than equivalent multiple subscriptions, i could connect more clients to one server (plausibly - still need to do tests to figure out how many subscriptions can be supported by cpp broker)
This would reduce the no of boxes required in a bigger deployment and directly help to reduce costs in large deployments, though few deployments (banks etc) ever reach such massive scales. Thanks gs ps : I am running some tests to try out the different scenarios and will post some results.
