The number one feature I want from VRChat+ is the ability to cast my desktop on to a surface in VR. Tools like VRCDN exist and work fairly well, but setting them up is involved and inconvenient. It is pretty annoying trying to use tools like OBS within a VR overlay. Lately, vrchat seems to be locked in a cat and mouse game with youtube repeatedly disrupting playback as well.
There is heaps of utility in being able to easily do things like:
  • play a youtube video on my own computer and cast it out to everyone, without needing to rely on "youtube downloader" type tools
  • play a flat game, like ps5 remote play or geforce now or on a powerful enough computer, even run a game locally, and enjoy the couch co-op kind of vibes like people could give tips on puzzles or just enjoy the social element of seeing someone reacting in realtime
  • show a photo
  • screenshare an app like blender or unity and get realtime advice from experienced players on how to problem solve or improve creative projects
  • put on an actual physical DVD or something and have a movie night analogous to IRL movie nights inviting friends over to my house.
Providing low latency video broadcast services is inherently expensive, so it naturally justifies itself as a paid feature. It doesn't feel like a nickle and dime thing to me.
On mobile and standalone vr i'd love to see the same thing supported, but offering the option of either an embedded web view getting captured, or on mobile devices where possible, integrating with the OS screencasting function in a similar way to apps like discord and streamlabs, so the whole phone UI could be captured and sent in world while the user could remain connected to immersive spatialised audio chat in world. Even better if it were possible to connect a second device like a tablet to the vrchat app and use that as the screen sender. You can imagine stuff like using webrtc to transmit p2p video directly between users devices so you get a really low latency view locally, where you could have a game running on an ipad that goes up on a screen you and your friends can see, that you could access on a quest standalone for example, as a more social version of the kind of AR pc monitor stuff that's becoming popular lately.
