I know the current Rackspace implementation was moved to django-cumulus, and there is a ticket to merge it back.
However, it looks like the existing RackSpace support in django-storages and in django-cumulus are based on the old "Moss" RackSpace API.
Is there interest in adding support for OpenStack files ("Swift") generically in django-storages?
There are available bindings I am aware of: python-swiftclient and RackSpace's Pyrax (https://github.com/rackspace/pyrax). I believe Pyrax would be good for direct RackSpace support, but Swift would work on anyone's OpenStack cloud.
