I don’t like to be the party pooper. But from my short experience with Meshtastic, I feel bandwidth is not enough for this amount of data syncing. I could be wrong though.
Negentropy syncing notes over meshtastic links would be cypherpunk af. fully distributed, p2p, signed application data over radio. Who needs ISPs? They are a chokepoint anyways. So many cool usecases to explore outside of microblogging.
Imagine a lora setup for a local community, syncing notes between each other without any real internet infrastructure in place.
To send a note would be simply writing it to your local database. When nodes are online at the same time they simply sync with each other or a local relay server.
You could totally build distributed, low connectivity, store and forward applications this way if nostr was used for your application data.
what meshtastic kit should i get to start hacking on these things nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 ? nostr:note1h4ullw8alkkkm7lxh6074p5mrufd2c80elx66kgjh3mdzcsgklask8c038

37.5 kbps is plenty
the bandwidth isn't the only issue, if you want to be a good radio citizen, you should be limiting you're time on air. in Europe that's between 0.1% and 1% depending on channel used. that reduces the bandwidth by a lot.
Isn't part of LoRa the ability to have many simultaneuos non-conflicting transmissions because of the chirp modulation and error correction codes? Or is that already taken into account?
Regardless, in rural areas this wouldn't be an issue.
Chirp spread spectrum modulation does allow for multiple simultaneous transmissions, but I believe that even so, with many devices transmitting together, performance can start to degrade, it will also affect other devices operating on the same spectrum.
