Library for multiple consumer oAuth?

Does anyone know a good and/or easy to use PHP library/class/whatever-it's-called for being able to do oAuth against a large amount of providers (Facebook, AIM/AOL, MSN, all the 'big boys', etc)? All it needs to handle is essentially authenti开发者_C百科cation, there won't be any permissions or anything - it just needs to be able to pull a login-verified username and a realname (optional).

Google recently released their Google Identity Toolkit, that handles several auth providers, it maybe come in handy. There's a PHP sample.
