Fun fact: a local /64 is fully enough to encode lat/long/alt
(24, 24, 16 bit) with about 2 m resolution. Add some minor
LSB bit jiggling and DAD, and you've gots yourself a rather
robust address allocation scheme that allows you to know where
you are, and mutal local node mapping. You can either store
it verbatim, or as deviation from idealicity. Implement long-distance
links by VPN tunnels initially.

Any current WiFi embedded is plenty capable of that.
