Sure there is. http://framework.qbix.com does it out for you out of the box. But then again, we haven't launched it yet, so I apologize... but reach out to me if you want early access.

However I should say that our framework takes a different philosophy. We believe that web apps shouldn't have to ask for OAuth access at all just to personalize the experience for you. They can ask the provider to display to you your name and everything else, in iframes that they can't get visibility into. Although I dislike patents, the whole system was non obvious enough to file one for the investors: http://www.faqs.org/patents/app/20120110469#b

We use oauth mainly for single sign-on, and the access permissions are actually a special case of an app requesting access to various streams you publish. In our framework, the app simply has a user id just like any other user, and can request access to your stream just like any other user. You can put users into friends, family, admins or any other roles, and then give them permissions on various streams.
