Evil geniuses and aspiring global overlords, your prayers have been answered. It's now easier and cheaper than ever to keep tabs on your legions of subservient minions. From the safety of your secret lair in the hollow volcano, technologies like personal tracking, GPS, and location-based services are yours for the taking. Cackle away, master.

A case in point is a company called Spime, which has just updated and improved its SUPL (secure user-plane location) software. SUPL follows the Open Mobile Alliance's recommended approach for passing user-location data over a wireless IP network, thus making your planned global deployment of personal tracking easier than shooting deathrays at do-gooders.
