Comment 3 for bug 1058510

It would be good to also produce such an index for clouds where we don't publish images, so that juju use is seamless everywhere. I've talked with ben & scott about using query2 for use with non-ec2 images, though its still not ideal, at the moment its focused fairly verbose with extraneous things and embedded build references across multiple files (http://cloud-images.ubuntu.com/query2/server/ec2.json). For openstack servers its possible we can glean some useful information from the glance server (http://docs.openstack.org/developer/glance/glanceapi.html#list-available-images-in-more-detail), but the contents of such are adhoc. At a minimum we need to know its ubuntu and its release series for a given image.
