So, we have one option, (IPv6+NAT44), no stuff needs fixing. We have another option, (IPv6+NAT64), stuff needs fixing. Maybe somebody needs to come up with a good justification for using NAT64 in the first place? (For networks other then ones with strange restrictions like 3G) Obviously, this is a very good argument for running NAT64 on an experimental network. >Why require IPv4 in the first place?

Let's make it such that the mail server that handles this list only accepts and delivers mail over IPv6. :-) Any of the current or prospective chairs willing to propose that? >> And complain about dual stack devices (like Android) that >> just don't support the tunneling protocol of the day. > >A device that just plain fails to operate on an IPv6-only network has >nothing to do with "tunneling protocol of the day". As far as I know, the only thing everybody cares about is IPv4 connectivity. That's why NAT464 was developed. Nobody seriously proposes to make an IPv6-only only network the default. At FOSDEM, usually the wifi in the big halls is completely overloaded. The best trick is then to go to the IPv6-only network, because nobody is using it. So, yes the IPv6-only option for Android would be really useful for FOSDEM. But not much else.
