IPv6 isn't what I wanted it to be (and I was on the IPng directorate). That said, it's what we have, and I think we *really* need something with a lot more address space.
At a very low, hardware centric level, IPv6 would be a lot easier to implement if 1) The addresses were 64 bits instead of 128 bits. 2) The extension headers architecture was completely revamped to be more hardware friendly. I hear a lot of noise about wanting to do 40GE/100GE with L2/L3 switching, but it is difficult to extremely difficult to implement hardware that can accommodate all the flexibility of v6 and keep up. IPv6 is a software architect's dream and a hardware architect's nightmare ;-) Bora
