I get very confused when I walked out the Softwire meeting this morning. Why did we only talk about making choice between 4rd-U and MAP? There are also several other stateless solutions, too. As far as I recalled, the Softwire WG have NOT decided to drop them at all. They should be discussed together and equally.
If the Softwire WG is going to choose single one solution, it should be choose among all these solutions. Until we have decided drop all other stateless solutions, this is not a two-horse race, yet.
