From the looks of you, you should be teaching the course, LOL. Maybe you could volunteer to give an afternoon seminar on self-protection at RTR as a prelude to the official get-together down the road.
I suspect Zen will be looking for instructors. A 4 or 5 day get-together would give people a chance to do some on-the-ground practice. Takes more than just book learning. The life you save may be someone else's.
