This is cool and actually something I have been considered missing during, e.g., academic conferences. The "hallway track" is often the most interesting one! Being able to wander around and overhear various conversations until you find one that interests you or you can add to is great. A Zoom breakout room is nothing like that experience. This, or something like this, could very well be what is needed.
