Well then if you want to do that, look at Mosaic for ideas too. "I did it my way" 🎶.

If other active developers went and built something like a Nostr 2.0 that wasn't Mosaic, but they at least looked at Mosaic, took what they liked, and had good reasons for not taking the rest, I'd probably be happy to dump Mosaic and go with their thing. But I'm unaware of any other next-gen project in the works. And most of these hard problems are not happening in nostr. I talked to a number of devs about future ideas. The Rostra guy is totally jaded and uninterested. Nuh wants to build on a crypographic filesystem (with pkarr of course).

I'm spending a lot of time in the fiat mines, but I'm still progressing Mosaic stuff. The spec and code are open, and the spec leads, so nobody can think I tried to jump start others. Truth is however that I'm the only person working on it, nobody else who has shown any interest has shown interest in helping to build it. So far at least.

I'm a few months out from having something to demo.

NOSTR is guaranteed, the communication underneath is using the same protocol. Meshtastic need to study deeper, have the impression they don't have public chat rooms but could be wrong (will check). Bitchat is open and also using coordinates, so integration should be possible.
