Thanks, Stacia. I thought I was the threadkiller for that thread. I couldn't find it and assumed it was deleted. So I searched "Motoyama" and found it again. I see that there was lively discussion after my post, and I was not the threadkiller I assumed myself to be. Glad you appreciated my post. Dr. Motoyama is very modest and consequently not many people know about his works. I happen to study with one of his students (Paul Grilley), who has been kind enough to pass on Dr. Motoyama's knowledge to us.
