Just to let you all know, I have put up a draft of Osamu's likely comments on the first few points up on the public pad. I'll add his likely comment to other points soon but I thought I would throw this up to give people something to work with. It's a first draft so may be tweaked, particularly the part about point 3 but hopefully this will get people going. Of course it's all subject to change according to discussion, comment etc.
