2-Step Verification is one of the coolest security features I've ever used and it's free. But it's not cool when I'm in my comfy chair at the end of the day and my phone with the authentication code is on the other side of the room charging. It seems Google is looking to solve this major inconvenience to my life by adding Bluetooth support to the Android Google Authenticator app and to Chrome and Chrome OS also.
As usual, it seems Google is dog-food testing OTP remote access on their own employees. Hopefully that means we'll see this feature launch soon. The Chrome OS-specific code is currently getting punted to later and later releases (now at R23 which probably translates to this fall).
