As for this program, here are my thoughts: If someone were to design a program that worked at most of the major airports in the country, a dedicated frequent traveler security program, then I'd vote for that. If you do not want anyone keeping track of where and when you fly, then opt out of the program. Of course, there already is a program that keeps track of where and when I fly: Delta SkyMiles!
