He wouldn't remember it, but Yokum spent a good chunk of time on the phone with me and my cofounders when we started Matasano, as a favor for a mutual friend. I totally agree with you.

Having said that, I guess I was weaseling my way around to the point that a boilerplate IP agreement would cost next to nothing, and would probably be all you'd ever need. People obsess too much about IP, and not enough about their own execution risk.
