I appreciate your comments, becoming aware of what consumers think about this idea was the entire idea of this post question.

Respectful rebuttals: 1. Criminals and sexual offenders are everywhere (see national registry) and I don't think being concerned makes me a "paranoid parent"....FYI- I have 3 kids.

2. Building this functionality into a cell phone is an exciting thought.........but any criminal can just throw it out the window, it has to be affixed in an "alarm system" type way----I am open to ideas.

3. Business Week and TechCrunch---wow believe they agree---have both suggested that there are significant safety/value benefits to such a device. The real issue is that for kids older than 5 it must be cool and customizable so they like it.

Lastly, infants dont roam but are often abused. (i.e. terrible environments, screaming, not being changed often enough, shaking, etc.) that the parent never knows about because when they stop by at 5:30 to pick-up after work all seems perfect. It is a huge deal!
