Hi Nick,

We should chat about how things are shaping up so far and how you're
implementing things on the other sides (consistency where
practical/possible).  Also, it sort of depends on the architecture and
use model details of Ceilometer, which I hate to admit but I'm not
really up to speed on.

My first reaction/thought is the best most appropriate place to tie in
is via the python-cinderclient.  There would be a number of ways to
obtain some of this info, whether deriving it or maybe some extensions
to obtain things directly.

Thanks,
John
