A very interesting point. In order to save precious CGN resources, it would not be surprising to see some ISPs asking CDNs to provide a private/non-routed behind-CGN leg for local CDN nodes.
For this to work, the CGN users would probably have a different set of DNS servers (arguably also with a private/non-routed leg) or some other way to differentiate these CGN clients. Lots of fun in the future debugging that.
Especially once you have 10 or 15 CDNs doing this, all of which have different rules of engagement. "Akamai requires us to do X, Hulu wants Y, Foobar wants Y and specifically NOT-X..." ;) And then Cogent will get into another peering spat and.... :)
