Yes, thanks all - it's great to see plenty of people putting forward their thoughts on this :). I agree that it is somewhat problematic to map the ETSI NFV use cases "as is" directly to the list of blueprints, finding an appropriate way to distil them into the hard requirements of the most minimal configurations of each is key. I definitely agree concentrating on doing this for a subset of them that are particularly well defined first is the best way to start off without spreading our efforts too thinly.
