No objection from my side. :-) It would have been great to also have it in 10 at some stage, but maybe that is rocking the boat too much. :-) I can maybe just tell about my experience. In our organisation there are about 300 people. About 2/3 are MS Windows and maybe 1/4 are linux and a few are FreeBSD. Oh there are a few Macs too. Our network is dual stacked. On the MS Windows, linux and Mac boxes nothing gets done, they just pick up IPv6 and work. On every FreeBSD box I have to "switch" on IPv6. A third of our internet traffic is IPv6 already.
