Well, advertisers couldn't use this without asking permission for a user's webcam, which would be a non-starter. I choose the less cynical path and say this could be tremendously useful for remote user testing.

Remote usability testing would be fantastic. This could be useful for local testing as well. Having a library or tool that could generically sit in front of a site to show where users look when taking action X sounds beneficial to me.

I can also imagine on a lighter note this being used for games where you look to where you want to move a character (maybe blink twice for confirmation).
