I would use Reticulum instead of Meshtastic. https://reticulum.network

Pros: - it can actually scale past 20 devices - Forward secrecy encryption - Is designed to support multiple underlying transport systems such as TCP or LoRa - Announce based routing rather than flooding the entire network which is order of magnitudes faster Cons: - Not as many nodes as Meshtastic has - Python implementation with no C implementation (can be speed up with cython however)

Is it legal in the USA? I seem to recall that ham operators aren't allowed to encrypt their traffic, that's one reason I never got around to getting licensed. Maybe LoRs allows for it because it's unlicensed?

Ignore me, I answered my own question. Encryption is still illegal on HAM bands, but legal for things like LoRa that are unlicensed (hence WiFi).

Nice, it took less than a minute to find a PDF of the docs. That's already more seriously "offline" than the alternatives.
