So the Zoom feature is cool. It's made for task-oriented things, like an activity divided into small groups and the person organizing it is the organizer of the event. It's highly structured. The analog version of what zoom has is a breakout session at a corporate retreat. The organizer of the event is in control and you retain your groups.

What I want to see is a user navigating rooms herself. The interactions I imagine are pretty different even though the functionality is superficially similar. This is early, I'm sure my thinking will change a lot. Thanks for the link though!
