Advertising Application for a Camera Neutrolizer

A grad student at Georgia Tech Shwetak Patel "is working on a system that will be able to detect cameras and shoot a focused beam of light at the lens, leaving the photographer with an artsy but useless pic of bright lights." Instead of light, maybe the system can be tweaked to beam advertising messages to the nozy photographers. Say, you think you are taking a snapshot of a new concept car at a closed trade show, but instead you will get a "hidden" message: "visit our website for more information".
