Ability to verify ownership of a github organization

As it is now, one can only verify github user status, and not github organizations. I'd like to be able to demonstrate that i admin (own) an organization's repo, and in the best application, all of the organizations that i admin on github.

No files, tests, or entry points are identified. Start by locating the existing GitHub user-status verification flow, then determine how organization administration should be verified and represented; done means users can demonstrate control of one or more GitHub organizations.
