Interesting. I guess the only question that comes to mind is how accurate is the calorie data, which is really what seems to drive this. Accurate calorie data is really hard to come by, unless it's specifically assessed in a lab setting. Ideally you can run a test group that uses the service for a month and weighs in weekly. Would add serious validation. Still, great idea and effort so far.
