graycat, would you mind putting an email in your "about" section of your profile so I can contact you? I have some questions about trouble I'm running into in regards to some of the examples you presented.
You first, and I'll read your "about"
and write you. For now I'm trying to
remain anonymous on HN. I may
not be able to help you much in
academics since I quit being a
college prof long ago and am
now a solo founder of an information
technology startup.
