In your previous mail you wrote:
Currently systems are often ipv4 only. One day they just don't magically
turn into ipv6 only boxes. Dual stack is the way the world is going
towards.
=> I can't see where/when I said I'd like to get IPv6 only boxes ASAP?
All of these have existing, _working_ IPv4 network implementation. No one
is going to just completely replace ipv4 with ipv6 one nice afternoon.
=> I don't want to replace IPv4 by IPv6 next month, I want to get
dual stacks as default ASAP. RFC 2553 is for dual stacks and
dual stack is the main transition tool.
You can run IPv6 only systems if you want, there is no market for them
today and in general they are dual stack systems with IPv4 not configured
(which is a bit different than disabled). I have some of them for DSTM
demos (a case where the difference is important :-).
The question is whether you believe in IPv6 or not: to ship systems
with optional IPv6 (i.e. dual stack) support is not a positive answer.

PS: (again) IPv6 is not a new protocol, IPv6 is the new version of IP.
If you believe in this (stronger than IPv6 itself) then you can really
understand the dual stack model (the integrated dual version model).
