>I use it to stream applications/webpages with my partner when we’re apart so we can watch a movie together by creating a high res vid/stereo audio input with no noise cancelling as the movie, then have her and I connect as lower quality, mono+noise cancelling participants. Each of us receives the video and audio of the movie, but only the audio of each other.

Ohh, shared media watch is still such a mess right now, and it would have been so amazing in the peak of the pandemic. Replying so I can find this in the future.
