I don't know that they're trying to drive a wedge between IPv4 and IPv6. I would think that even NDN's supporters see it as a very long-term, post-IPv6 development. I am surprised however to see Cisco supporting this. It's one thing to have some academic networking specialists writing papers about NDN, but for a major corporation to devote resources to a 10+ year development project with an unproven architectural basis strikes me as odd.
