Hmmm . . . sounds neat, especially if you hook up the receiver to a recorder; you could really get a "bird's eye" view of your neighborhood.
Is it just me, or is this going to raise some hackles in government circles if someone DOES make a commercial kit out of this? Think of a budget-priced TV-guided bomb . . . though I assume it's been thought of already by the well-financed terror groups. Or maybe for smuggling small but profitable amounts of drugs across the border, with reduced chance of getting caught?
