Such behavior is obtained via a common loggin system. On Gmail a lot other (like StackOverflow), they use OpenID, some other uses OAuth like Twitter.
But, I don't know if you're allowed to access user's data, like your their Gmail address. I've never used OpenID before.

This would only be possible if Gmail had an API for it. You can't read an other domain's cookies, for security reasons.
