As an example, when using volumes with compute, you may want to schedule an instance based on both compute and volume information.  This type of scheduler doesn't belong in nova because volumes live outside.   

Sounds like a discussion for Portland ! Please don't add more to the
already-full grizzly Nova plate :)

Knows about all the things and give mortal services answers to their
questions about the future... Sounds like the name for it should be
"Oracle". Unless that's already taken, in which case I'd suggest "Pythia":
