Neil	Lor: you make your xbl dispatch a custom event
Neil	Lor: your extension has a capturing event listener for that event
Neil	Lor: it calls preventDefault() on the event if the site is not in the whitelist
Neil	Lor: and also stopPropagation() to stop the site seeing the event
Neil	Lor: then, the xbl can call getPreventDefault() on the event to see if the flash should be blocked
Neil	Lor: this still lets the site see if its flash is blocked, of course, because it can do the same thing


	rue2	see, it's not just "an object". it's an object created with a constructor that formed closures for all the member-functions its constructor instantiated
	rue2	oh
	rue2	yea- i did solve that
	rue2	if you load a subscript via the subscriptLoader, and set the object as a "const" it can't be deleted
