Show HN: Flask-Dance - Easy OAuth with Flask

This is nice. Also see [1], which implements Oauth provider.

I have yet to find a solution that makes it easy to implement a "two-legged oauth" provider with Flask, e.g. one where the user does not need to authorize a token, like in the case of using oauth in your company's own apps.
