The Chromium OS Team is thinking about adding a nice new feature called internally consumer management that will
let Google help you remotely lock, erase, and locate your Chrome OS device.
To see it, you'll need to switch to Dev channel, turn on Dev mode, run chrome with the experimental command line switch¹
--enable-consumer-management (not a flag there) and go to
chrome://settings.
Since this is still work in progress, clicking on the "Enroll" button won't do anything yet though ;)
