But basically when your bento HTML first gets saved, it generates a number of keys used for managing the permissions to join the Cloudflare DO. You can then send out an invite deck with a key that allow other people to join (with their own generated keys). With this architecture, you can revoke people's access, as well as giving them only read-access to the sharing session for example.
Would love to know more about how this works then? Is it more or less encrypted P2P?
