I think it has to do with the medium. Maybe the answer involves coming up with some sort experience that doesn't feel as dry and disconnected as video conferencing. This is where the idea of course becomes hand wavy -- but maybe it involves some use of AR, or a projector -- who knows.
If I were in your shoes I'd be thinking about a game-changer, instead of an incremental enhancement of video conferencing. Maybe that's bad advice, but I know I don't find this offering terribly compelling.
