I can see you really want to look the other way, but seriously, you seem to not understand how determined some cheaters will be. If you as a student, use MOM's iPad to do it, or your little brother's kindle, or your boyfriend's android device? The point is, if a student KNOWS they're being watched, or if they SUSPECT that honey pots exist, they just go borrow a device from someone completely unrelated to their normal day-to-day usage, and they're golden.
BTW, this arms race has already given rise to proctoring services that use the microphone and camera on the testing device. Far more draconian than TFA. Not that I support cheating in any way... I just think the solution is on the other end. Fully randomized questions for online tests. Depending on the subject matter (say math, chemistry, poetry) it's really not that hard to permutate questions with roughly equivalent difficulty levels. My calculus professor did this regularly by using the same problem, and even the same pictures, but simply providing different inputs (like length of a pipe or whatever) The problem is teachers/professors are lazy and don't want to do the work to produce unique quizzes, or they employ aides to do it who are on the take.
I just think no mater how you slice it, the "establishment" is always going to be on the losing end of a technology arms race.
