I agree with Leslie on this. It is important to approach this in the right light. Not an interop event; that would be for the implementors of the products. Not a demonstration that IPv4 is still required for most things; we know that already. Not a one hour session where thousand people try to install something new at the same time without a network; there needs to be better model for that. But I think we should still do something. I viewed Russ' call as an opportunity for the IETF community to take a challenge and see what we can make happen by IETF-71. As a personal note, I've had IPv6 turned on my equipment, home site, and company site for years but during the last few months I have tried create a situation where most of own communications would be on IPv6. We converted the company mail servers and gateways that I use to dual stack; some of my own web systems got AAAA records too; I ensured that the tools that I use have the right capabilities and defaults to use IPv6; I've contacted the admins of the remaining IETF web sites that still are IPv4 only to ask if they can be converted to dual stack. A significant part of my communications go over IPv6 today, and I have a hope to get this to cover most of my work-related communications. And yes, there's pain. I'm typically the first one to experience the firewall config bug or routing issue on the IPv6 side. But I'm willing... So, I would suggest that we focus on the positive opportunities that Leslie mentioned. Get more things to work. Challenge sponsors to do so as well. Solve some of the remaining problems. Educate ourselves both by doing and by seeing what others do or where they fail. See what works in IETF-71 (but the format of that is less important). Obviously, this needs planning -- Russ' mail is not the plan but rather a call for us to figure out what would make sense. Much work needed... I'm also somewhat surprised by the reluctance of people to try things out. Where's our sense of adventure and eagerness to do new things? We are engineers after all, tinkering with network setups should be fun, no? Boldly go where no group of thousand has ever been... Or at the very least, lets change something for the better.
