Right, we are on the same page. OpenID won't be used, period. It might or might not be offered, but only to infrastructure systems (like the wiki, etc). That decision is out of scope for Birdshack.

OAuth might be used. When I read the basic architecture, it claimed it would do crypto authentication using fixed public key pairs. If this is what it does, we'll be fine. If not we'll likely replace it with something that does.

In my mind, for now, this probably means that the only apps that can access the API will need to be registered. It won't be totally open.
