Idea: Nostr over nomadnet / lora.
For local vexl (p2p btc otc) and nomadic service providers (consultation, massage - h/t Bearetta 🇨🇿 or anything else). You arrive somewhere, broadcast a note locally.
Very hard to surveil centrally, but identity and reputation can be kept.
Could be useful as a local relay. Want to meet with nostrich friends? Broadcast a note over the air and only people more or less around you see it.
The idea is similar to truck drivers using radio to snitch on the locations of cops, or traffic jams.
