> Several providers have a copy object semantic that works within one datacenter/region.
> * [Azure copy Blob|http://msdn.microsoft.com/library/azure/dd894037.aspx]
> * [OpenStack Swift object copy|http://docs.openstack.org/api/openstack-object-storage/1.0/content/copy-object.html].
> I have not dug into Amazon S3 or any others, so I could use some guidance there.
> I'd like to design it to be used cross-providers instead of ex_copy_object, as discussed

> I'm imagining that the StorageDriver class would get this function header:
> {code:title=libcloud/storage/base.py|borderStyle=solid}
> class StorageDriver(BaseDriver):
>     ...
>     def copy_object(self, src_container_name, src_object_name, dst_container_name, dst_object_name):
>         """
>         Copy object from one container to another (or the same container with a new name).
>         :param src_container_name: Source container name
>         :type src_container_name: ``str``
>         :param src_object_name: Source object name
>         :type src_object_name: ``str``
>         :param dst_container_name: Destination container name
>         :type dst_container_name: ``str``
>         :param dst_object_name: Destination object name
>         :type dst_object_name: ``str``
>         :rtype: :class:`Object`
>         """
>         raise NotImplementedError(
>             'copy_object not implemented for this driver')
> {code}
> That layout works for both OpenStack/Rackspace/HP and Azure, minus any additional metadata
headers that you might want to send for these providers. Is there a clean way to handle that?
