Polite Cell Phones

The post title seems like an oxymoron I know, but Slashdot is reporting that some research is being conducted in order to create Polite Cell Phones. I was in a conversation with someone a couple of weeks ago and they mentioned that certain places (churches were specifically mentioned) should purchase and use jamming equipment to disable phones whenever they feel the need. With Bluetooth becoming more and more popular, and cheaper as well, I don’t see why they don’t create a standard protocol for something along the lines of “accept location volume settings” and then places such as theaters, restaurants, and churches could broadcast there preference. With the quality of cell phone hardware getting worse and worse, in a few short years, 99% of the world would be compliant. Surely someone smarter than me is working on this already…
