Jami’s feature set seems perfect for this WiFi mesh network, but FCC regulates the Amateur Radio spectrum and no encryption can be used on these bands.
I should have initially stated I am not requesting support, just a technical response as to the feasibility of disabling the encryption from the source code.
AREDN is a regular a WiFi TCP mesh that can (or cannot be) tunneled to the internet albeit without any interference from public consumer wifi (0.5 watts) so back haul links can travel much further (up to 1500 watts) and local data will flow faster.
