We have a spec covering some of this:
https://blueprints.launchpad.net/nova/+spec/ec2-id-compatibilty

It's "Essential", assigned to Soren and targeted to diablo-3. I'd love
to hear his thoughts on this :)

Vish set that spec to "Essential" because the current situation was
supposed to be completely broken, but reading you guys, it appears not
as broken as expected ? Should importance be downgraded to a "nice to
have" ?
