Thanks, Mike. This is great feedback.

I wonder how strong is the dependency between the cinder driver and
bricks. I mean, it'd be cool if we could complete the implementation in
a perhaps not so optimized way - on top of cinder's API? - and then use
the bricks library when it's done.

Thoughts on the above? It sounds hacky, I know. :)

Cheers,
Flavio
