[At-Large] English summary of Japanese MIC effort on v4v6

Hi, Here attached is a English version of a presentation made by Ministry of Internal affairs and Communication (MIC) of Japan, as of December 2007. There are newer information/reports published in January, but still all in Japanese. Look at the last few slides, in particular # 17, giving some findings of the Working group comparing different technical approaches and impact assesment to the users. These works are carried out by some 20 panel of experts, ISPs, service providers of various kinds, with academics. I was not involved at that stage, but will be joining soon for the policy discussion. izumi
