I think this could be done with a separate bluetooth device with a vibrating motor built in. It would be a similar product to trying to solve the other major issue with phone calls being heard. If someone often stores their phone in a backpack or purse instead of their pocket, vibrate is useless. Also, most of the time these people do not hear their phone. It can be kinda annoying when your trying to reach them in a noisy establishment. Why not make a super thin bluetooth/vibrate device that can hook onto a pocket (or whatever) so calls are detected every time! (and could be a pattern as well so you know who is calling) There would also be a different alert with text messages.
