That's a clever solution. And there's a corresponding revIDEUnsubscribe 
message as well as a revIDEUnsubscribeAll for when you're done. I don't 
believe any of these are documented, but they're useful and, in my case 
at least, essential.

For now the subscribe messages are limited to a predefined set of IDE 
messages, but the long-term plan as I understand it is to open up the 
mechanism to allow for user-defined messages as well.
