Nostr over Reticulum network would be an interesting development. Certainly some technical hurdles to work through, but the payoff could be substantial. Reticulum currently has the NomadNet which can serve as a static site or BBS, but in general, group chat or collaboration is pretty weak for Reticulum (based on what I presently know about it). Nostr could be that group chat, persistent messaging, community building, micro-economy tool that could also bridge Reticulum node relays to clear-net and/or I2P relays if so desired. This is something I would like to ponder for a while...
