Why restrict this to just two? Why not have the whole pizza pie of them?

At least I see three could be very useful, e.g. for kids in the backseat if they share a tablet for entertainment on the road.

You can of course add >2 support later.

@semi-extrinsic When brainstorming with Netizens R&D team (I took even took a picture: velo.audio/img/IMG_4309.JPG) we were totally talking about a pizza! However, it needs to be tested. It's too early to say, how many devices can we connect to each other without a delay and other potential issues.

Sure. If you work out how to run with three users nicely, you can maybe extend to many by making a network topology like a tree that forks off two branches per level; that gets you to 8 users with only 4x the delay of 2 users.

Another idea of shape (with also sharp angles) is the "Two Piece Pyramid Puzzle" http://gamesmuseum.uwaterloo.ca/VirtualExhibits/puzzles/pyra...
