I would hope there is some regulatory concern about flights over populated areas. Yes, there are a number of ways this concern might be addressed, but like everything else, I expect the FAA to be really anal about it.

I also hope they are concerned about potential remote hijacking. It is probably desirable that these things can be overridden by a human operator, rather than solely relying on the flight computer. But that opens the possibility to attackers as well.
