Possible to create secret gists only accessible to org members?

I know you can make secret gists, but is there a way to make gists that are only viewable to members of a specific org?

Doesn’t look like it’s possible. “Secret” means just “not publicly advertised” and “not shown in search results”, but anyone who gets hold of the Gist’s URL will be able to see it. So, accounts plays no role in the secret vs public distinction, I’m afraid.
