This is super cool and thanks for open sourcing. I remember seeing CoScreen & Screen Hero here on HN years ago and thinking it was absolutely the cat's pajamas. Unfortunately, I think it was one of those cases of being blinded by the tech being super cool.

Of the ~decade since I've seen these types of apps, I've never used one and, frankly, I never ever craved for "just sharing one window" or "playing in multiplayer" as @jsherwani put it. Which is kind of odd, because COVID came and went (peak remote/screen sharing days), and I had totally forgotten these kinds of products even existed. While this is (still) super neat technically, I just don't really see a concrete use case other than "lemme show you something super cool."

Has anyone actually used it? Where would this kind of tool be better than just screen sharing over Google Meet or Discord or Slack or whatever?
