eyePhone

I'm surprised thinkgeek hasn't thought of this one yet. Simple - bluetooth headset built into a spectacle frame.

Take it one step further - a full-fledged head mounted display that you can use glance and blink to control. How about that? Of course, form factor should still be a normal pair of glasses. Something like Mission Impossible? If Cruise actually had an iPhone in that movie, it would have made sense to some people.

TI MSP430 Enables Secure USB Data Stick

Surprised it hasn't been done before. Use the Chipcon radio's RSSI (if available) to get an idea of the distance. Then, (you carry the base station on your belt or in your pocket - it never leaves your person), if the MCU detects the distance between you and your USB stick is more than X, it starts screaming. Simple, elusive. You see, there needn't be any layoffs at all. There's plenty of worthwhile work for everyone.
