I don't know him well. He might recognize my name from posting on ITFORUM, but I'm not sure how closely he monitors that list these days.

I think his interest might be more generalized as being in "agile" processes of which XP is a subset. Hmmm... "agile learning"?

I don't know exactly what he's working on right now and I'm not sure how he would react to an approach. He's always been a respectful, thoughtful and perceptive poster on ITFORUM.
