Cellphones the new breathalyzer?

Could the police one day use cellulars to detect alcohol? According to sibling site Engadget Mobile, the mobile company NTT DoCoMo has developed a cellphone that has a built-in breathalyzer. Originally designed for bus, taxi, and truck drivers, the sensor detects and measures the amount of alcohol present in the driver's breath and transmits the information to their supervisor. It wouldn't be a great leap for the technology to be offered to police or to parents who could verify if their children have been drinking simply by calling them.
