Maybe it's like face-recognition - that's been 'working', kind of, for ages, but still mostly isn't very good and not very impressive. And that's a field where anyone with a scanner or camera can play. In a field where you need a special uncommon (to the point of needing custom manufacture) bit of hardware before you can even start work on the protocols, I imagine progress would be slower.
