I know I'm putting the cart before the horse here, I realize grouping capabilities is something in the works but I just got a unique request that made me think about something. If and when a grouping feature is released, how refined will the grouping capabilities be (if that can even be answered right now)? I had a Faculty member ask if I can lock down a group by our active directory groups so only students enrolled in his class can see his particular meeting room. I know we have password protection controls available on meeting rooms but I think they are asking for something a little more advance than this. I think the concern is that passwords are only as secure as the students enrolled in the class.
