You're getting dangerously close to an idea I had back in 1991, when I was working at the Defense Information Systems Agency, in the basement of the Pentagon. I talked to our security officer, and he put me in touch with a guy from the intelligence side of the house. I explained my idea, he said they already had something in that space, and that I shouldn't say anything more about it to anyone. I never heard anything further on that subject. To this day, it is one of two things I don't talk about.
