More than happy to help out, I think we are on a good path by focusing on the current BP's we have. I will not make it to IRC meeting today, but will comment afterwords. I think Adrian also pointed out one other point just to put on the table so we set the tone and scope accordingly, that is some of these BP's while being NFV related and not NFV essential but also benefit the generic cases too imho. For example the port-mirroring is in some cases a feature "some NFV services" would utilise" (lots of strange stuff in the wild :-) ) this and others would never need 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.
