Have you seen Meshtastic (https://meshtastic.org/)? It seems like a similar concept but using dedicated devices and unlicensed ISM frequencies, and it's a proper mesh network (so you can even setup repeaters to provide better coverage for an area). I guess they wouldn't work too well if you're travelling to another country since you'd have to get the right radios for the country but it's a neat idea.
Furthermore, the latest build of Meshtastic mentioned some LAN networking, so nodes that don't have radios can still exchange messages if they're connected by some other means.
That seems just a hop skip and a jump from having a Bluetooth WPAN/WLAN that lets many phones share one or zero Meshtastic radios but still be able to talk to each other...
I've been checking out https://reticulum.network/ which does the same thing as meshtastic, but encrypted. Looks like it's in the early stages though.
