I have been saying that a keet.io integration would be nice, I'm surprised and confused why it isn't obvious, unless I'm missing some major flaw with keet.
It would embed just like a video, you can click play and your nostr client (like amethyst) would pull the data straight through keet, not through nostr relays themselves. You could even have a join button that let's you be one of the participants or something.
It could be our version of spaces, only with video and no central host. Nostr would just serve to help people find each other, not needing to host the data.
