Just my opinion: I just saw one video [1] so I may be misjudging or misunderstanding: When posted in 2007 there were many open problems yet. I hardly think that all the benefits would be real benefits and most things can be already done and it doesn't solve the most intricate problems of today's Internet. I wonder if it could really be fully trusted. Sounds nice and all, but I'm having trouble constructing it in my own head. What about live content (multicast), what about I as an end-user being able to certify my own information without relying on someone else? How to get the initial certificates, signed and trusted? When I request everybody near me to get some info and nobody have it, will everybody ask for everybody near each of them? And besides, most of the problems he describes can be solved by inserting a layer between 3 and 4 (something based on the Host Identity Protocol and its DNS records). It's still a change of paradigm but a smaller one: instead of connecting to hosts, connect to services that can be provided (dig -t ESRV) by many hosts each of which may have (dig -t AAAA) many physical addresses. You set up a tunnel with internal signaling between end hosts that have multiple addresses and there you go: automatic path resiliency on both sides, automatic L3 mobility with connection persistency, some basic automatic encryption for all connections among those two hosts, all without requiring PI addressing (BGP would only be used for Internet providers and big sites)... It would scale and all that is needed is some changes in the OS, not applications, not the whole Internet. No need to justify equipment acquisition because it is end-to-end. The infrastructure doesn't need to be updated at first, but would need to catch up. Internet could be forced to catch up and if done properly, this gives automatic efficient addressing with a drastic reduction of the global routing table and automatic BCP38. IPv6 could be an excellent opportunity to get this working. [1] https://www.youtube.com/watch?v=gqGEMQveoqg Best regards.
