Google Researchers Propose New-and-improved CAPTCHA?

Well, here's an interesting article on Google researchers and their new proposal for improved captchas.

I really hesitate when it comes to captchas, whether it be from the user's perspective or the architect's. Present-day implementations are often too difficult or troublesome to deal with, and on the flipside, are all too often easily defeated by employing underpaid serfs in a sweatshop. But the gist of the article is that the new proposed captcha is image-based, which is great since text-based challenges have many shortcomings (language-dependent, requires text input).

I hope that Google can roll out some kind of library or package for this idea, it sounds pretty solid.
