Neil,

Wilf just took the words out of my mouth and re-typed them in a more concise and logical manner.

I read this skeptically, originally thinking, "oh boy, here we go again - another bright COIN idea pushing 'COIN skills'." I expected to disagree point by point. However, this seems straightforward and practical.

My only reservation, again, is what Wilf pointed out regarding the fundamental assumption, but even that doesn't seem overly troubling to me.
