Concerning the question of objects A and B, and the time it takes
B to realise that A is gone, consider the following (lightly though!)

	Given that recently (50+ years) we have compiled some
	accurate astronomical data, does it not follow that 
	we could take a known event of stellar proportions such
	as a nova or supernova and track it out to it's
	corresponding actions on the red/blue shift of a 
	nearby star and thus measure the time delay?
		Since the distance to nova A is known,
	and the distance to star B is known, and thus
	the distance between them, the earth-object
	times are known and thus of no importance, and
	the object-object time becomes the control.
		If the change is very slight, which
	is very likely, do we have a means of accurate
	measurement? Would the space telescope provide
	the nessecary level of discretion?

This is my first attempt at net communication, and I can only hope
that somehow it will get through.
