HP Device Automagically Blurs Face In Pictures

HP has developed a device that automagically blurs your face in pictures, which if you were a celebrity would be great for anonymity. Unfortunately once you read the article, you realize that the magic is that the device sends out a infrared signal to cameras that support the feature, and then the cameras will blur out your face. So basically, this won't work unless 1) all cameras support this functionality or 2) the camera is close enough to receive the signal. I don't think this will work.
