I've mentioned making this exact thing many times to my wife & friends. Instead of iPhone, I wanted to do real-time video from a hidden cam with the processing done on a remote PC. Imagine walking around the town and casually saying "Hey Sharon" to some random girl while she and her BF both wonder how you know her name. Would be pretty funny.
