I don't understand how this can work. Surely my subscriber applications have to listen to the same notification name that the publisher is going to notify on (unless I am missing something about how NOTIFY/LISTEN works). Yes I know you can construct that name dynamically prior to issuing the NOTIFY but if you are changing the notification name then how do the subscribers know what names to listen on? Do you have a quick example of your suggestion?
