The Future of OAuth 2

GNAB is a work effort within the ITF that is, I think, in many ways an attempt to re-envision and re-design and rebuild OAuth from the ground up. It's something that Justin's been heavily involved in and pushing for. GNAB is not OAuth 3, although it does attempt to address many of the same kind of problems. So there's certainly a relation there, but it is, I guess, independent effort towards some of the same ends.
