	Splitting the application in two rx/tx physically isolated
	devices is clever...Although using two laptops or two
	raspberries seems a bit overkill?

	Now I'm wondering how easy it would be to hack a
	microcontroller through its serial link. Of course "a
	microcontroller" is horribly vague. For instance, what about a
	microcontroller that can't execute code from ram?
