It'll be interesting to see how this feels for collaboration compared to current video chat. It clearly has the advantage of allowing people to 'interact' with things in the space, but you lose the feedback aspect of people's facial expressions. With video, especially in a group, you can see if people are following what you say, nodding or shaking heads, have confused looks, or are not engaged (or falling asleep). Compared to voice-only discussions, for example, sometimes people won't ask the question if they're confused, presumably thinking they're the only one and don't want to waste others time and/or embarrass themselves. Maybe facial expressions can be emulated -- but there's a very big uncanny valley to get over to make that usable.
