Oculus recently posted an OBS Plugin and Android app that will sync a real camera position with the game scene, and then the Quest creates a 3rd camera. It sends 2 layers of visual information to the OBS plugin, being in front of & behind the player, which OBS then composits with the real player on a green screen, to make it look like the player is in the world.

As a developer, I'd like the ability to use a similar system to send that 3rd camera to the PC as a normal scene view - no OBS or real camera required. This will allow my users to broadcast games from a spectator view, which is much better than first-person view. It can be used by users who don't have a greenscreen or want to show their real bodies.
