I think we should look at relays that are discoverable over mesh / zeronet / multi peer / Wi-Fi Direct / wifiaware / second wind.
I’d love if we used some for the nostr grant fund put money in to projects to develop a offline functionality for nostr. Using embedded relays and ones that could go in to lower power devices like raspberry pi for places with limited connectivity.
It would mean that nostr could work in areas without internet or web the internet gets shutdown
