The next step to all of this is an Oauth provider that's built around privacy. Imagine if you could sign in to apps with something other than facebook or google. "Sign In with " would be awesome. It's all technically possible today, and Mozilla nearly did it with persona, but gave up for some reason.
If anyone wants to fund this, for a mere 10-20 million USD I think it would be possible to create the service and market it to enough devs and end users to get traction.
