Nym.bar is a totally separate web app, with no mesh or location features at all. It uses the Nostr ephemeral chat system.

Never heard of it or tried it before. Definitely not what I was criticizing because I don't know enough about it to say anything.

the real elephant in the room is does it even work? 😂 where are the boots on the ground, download counts does not equal success.

Amethyst also has some basic support for ephemeral chats. It would be cool to have that built into more clients, plus a way to easily run your own relay focusing on them over Tor. IRC style communications over Nostr.
