I came here to say this as well.

I am using Virtual Desktop with a proscenium theatrical cinema virtual environment and sharing the Capture render screen 2D flat. I mimic 3DOF from a fixed position in the theatre. I have invited other headset users to a similar experience using Big Screen. (Which is a lot more wired fun.)

However, if the render view "Camara" in Capture could stream RTMP or RTSP, then I could live stream a virtual programming session to multiple headsets on my network or OBS to Twitch/Youtube. 180 3D 3DOF would be exciting, but I'd be happy with 180 2D. I want to give the auxiliary viewers the experience of sitting in the venue.

I'm faking it now on my Quest. I started doing this with a GO.  But with an Apple Vision Pro and virtualization using pass-through AR making their way into the curriculum, I see many more applications for Capture to be the industry leader for lighting design students. It already is for us, as 1 theatre with 1 lighting console makes it difficult for 10+ students to learn. 

Would be great to be able to have a VR option in "real view" for client presentation.

I agree that would be grate to have VR option.
