They hard part is getting all the end nodes to use IPIP tunneling as their primary protocol by default. It is doable but that is the hard part.
Actually, both methods could exist side by side. If a standard packet arrives, the destination AS is looked up using conventional routing information, it is encapsulated and sent to the destination AS. In other words, a standard packet is assumed to be a legacy address space packet. An encapsulated packet handled in the new way. But you know, the fact that the network techies has not exactly spent the past 10 years busting down the doors for v6 should tell people something really important. That they are willing to wait until the wolf is at the door to switch means something that needs to be paid your attention. v6 could well be the protocol that broke the Internet because it is sort of like replacing a Jeep with a bus built by Rube Goldberg. That adoption is so low at this point really says that it has failed.
