I would encourage DevStack support to be implemented as an external plugin in the stackforge repo directly if they want to do the integration.  This would allow local devstack runs to use it directly even if it doesn't get in to the CI gate.

Most of the EC2 exercises in DevStack are broken and I plan to go ahead and remove them soon, plus disabling n-crt and n-obj which both only exist to support euca2ools bundling.
