Michael, For a change I mostly agree (will detail below what I don't like) with what you just posted, especially:

Quite possibly fatally. The same is true if we create a swamp again and allow individual /48s in the global routing table. Then IPv6 will become IPv4 with more bits, and in the current economy the net result will be more NAT-aware apps. I'm sorry to say it bluntly, but today IPv4 is unavoidable and if the only edge IPv6 has is a bigger address space I'm afraid it won't be enough to cut it. I welcome some debunking on the following assertions: 1. Even if we say that NATv6 is evil, there is little we can do to prevent it from happening except providing a solution that would bring somehow similar advantages. 2. Even if we say that individual /48s in the global routing table are evil, there is little we can do to prevent it from happening except providing a solution that would bring somehow similar advantages. However, 3. If we say that NAT is acceptable, half-acceptable, maybe OK in the short term (or whatever) it WILL happen and there will be no way back. 4. If we say that individual /48s in the global routing table are acceptable, half-acceptable, maybe OK in the short term (or whatever) they WILL happen and there will be no way back. In other words, it IPv6 becomes IPv4 with the same NAT crap and the same BGP stability issues due to an oversized routing table, it ain't part of my network designs. Back to what I disagree with, you seem to blend the PI issue and the SL issue into the same problem. They are unrelated.
