That sounds cool if you've got the application and the budget, but
looking at it another way: for the price of an expensive unit, plus
monthly service fee, using only a few billion $$ in infrastructure,
you can be connected.  Sounds like cell phones.

I don't see how this can "humble" or even compare to APRS; they are
very different communications systems.  As I tell my students, if I
have two D7s I have a complete digital and voice communications
network.  Doesn't matter if natural disaster takes down the cell phone
towers, or if i'm on the dark side of the moon or mars.
