swift/S3 cloud-wide storage

[Marcus Sorensen]

What's the issue on this with never being able to reconfigure it
again? If I change my key or something in the database, does that
work, or is there some technical reason other than no UI set up? I
don't understand how it works well enough to get why you can't add it
after the zone creation, or change your credentials/S3 provider
afterward.
