	It depends - see below.

	Correct - it is already defined as part of DisMan.

	I believe the DisMan table can only moitor scalars.

	The same way you would implement a get for the same object.   If you want to emit the notification for certain values of the object, or just whenever it changes, put the check in the commit phase of your set handler.
