Project Byzantium did some research on it a few years back.  We tried
AX.25 over FRS, GMRS, and modulated laser light.  Legality aside (we
took steps to mitigate interference, but it still should be mentioned)
they're not useful for datacomm (especially in emergencies).  Amateur
radio, while having a higher barrier to entry, seems to present a more
feasible set of implementations.
