I've posted my MX on the Rocks presentation here. One small note - I think I may have made a mistake during my presentation. I know I made the mistake when I was writing my code.

Anyway - I was trying to show that a private method defined in a CFC would not show up in a child cfc. This is not the case. In fact, CFC private methods act like Java's protected methods. There is no way to make the method exist only in the parent and not the child. I believe I may have said the opposite at the presentation, and if so, forgive me. I had a brain fart!
