A couple more things

There are a lot of uses for a device like this. The health-benefit one mentioned here is a great one.

NASA Device Could Be Used to Monitor Health

NASA engineers have developed a small monitoring device that can record a wearer's health information and transmit it to physicians in real time, Wired News reports. The Crew Physiological Observation Device can also alert the wearer of dangerous changes in vital signs such as heart rate, blood pressure and temperature.

Users can attach the CPOD, which weighs 2.1 ounces, their waists and then plug lightweight medical sensors to the device, depending on what they want to record. Information is then wirelessly transmitted to a computer or handheld device, which physicians can monitor. The software can also be programmed to respond to certain data changes and alert a physician via e-mail.

Interesting.

But then there's this, which is a travesty of our prison systems' pretense to "rehabilitate" inmates.

And what the heck is it with "reorganizing" a class so successful that one of the participants won a national prize for their work, hmmm?
