Some of the points you bring up do not seem to make sense. CDN's not only cache traffic, but also optimize transport. There are huge benefits for this function, even with video traffic. Also, caching is probably not appropriate for IPTV, but YouTube clips can be cached, particularly instantly popular ones that are access millions of times a day.

Also, there are network features to work in conjunction with CDNs. What if a CDN accepted multicast data from an IPTV ISP and then turned that traffic into unicasts at the local level, where broadband could handle it. Or vice-versa if the core has more bandwidth and the end-points can support mulicast.

Yes, caching may becoming less important as a point technology, but that hardly indicates the death of CDNs. I see it as a natural migration. But your paper implies the death of CDNs because they can't cache as efficiently as before. I don't see it.
