It is not possible to use Swift as block storage, because you access
files (objects) stored in Swift only via HTTP interface. So you can
upload new files, delete existing files but you can't update files in
the middle, without reuploading it fully.
So I guess use case for OpenStack Compute implies storage of initial images.
