[Openstack] Federated Identity Management (bursting and zones)

I'm curious about the interactions from the user side with OAuth (cmdline)

Unless there's work underway on this already I wouldn't mind throwing a BP/spec together on how this might work (if possible).

Any objections?

Agreed, Pluggable option 2 with a default OAuth implementation seems like the best strategy.

I was thinking of having OAuth implementation for authorization/delegation in an external identity management solution, option 2 :). The IdM solution can be extensible to support other Identity Federation protocols as well such as SAML.

4. Use OAuth?
