If the log-into chrome would just reflect the login state into google's services, I think it would be much less controversal and actually useful. Imagine little indicators that show which identity providers you are logged into, like Facebook, Google, Twitter, .... You could do this by passively reading the site cookies in an extension (are you allowed to do that nowadays in extensions?). Even better, if you are not logged into, say, Facebook, block third party cookies from their domains so it's harder for them to track you. I think I have a good idea for a weekend project...
