Noticed $subject. Is it the case?
I'm hardly the expert here, and this probably makes more sense to some of the Rackspace folks on the mailing list. But just to clarify: would this be the same type of "region" as referred to in the Nova command line client docs [1]?
--os-region-name <region-name>
Defaults to env[OS_REGION_NAME].
Could you give an example of how you're looking to *use* this region property?
