I don't think that anyone is saying that cloud admins are going to be
forced to deploy and maintain an external SDN controller. There are plenty
of deployment examples where people are just happy with network
virtualization the way Neutron has been providing for years and we should
not regress on that. To me it's mostly a matter of responsibilities of who
develops what, and what that what is :)

The consumption model is totally a different matter.
