I would not be surprised to find out some years or months down the road that the government studied the system and stole it, clamping TSCW classification on it and installing it all over, but with some government operative substitute for the citizen spotters. Remember INSLAW.
FYI Jay Walker and Walker Digital were the founders of Priceline. I've met him and he's one smart guy so I'd sure listen to him if I was some DC desk jockey.
That is entirely possible. It might even be a better answer than citizen spotters. I wouldn't want a citizen spotter named Mohamad guarding a chemical plant.
Of course, the government would give an expensive contract for the installation and maintenance to another company along with the technology and exclusive rights.
