+1 I think he could do an amazing job with a dvd. One of the things I've appreciated in his teaching is getting the "why" of a technique and not just the "how." When there are details in a technique he teaches that differ from the "standard" or maybe more common way, he always explains why he does it *this* way; what the advantages are, what the disadvantages of the standard way are, etc. I think that would be very useful for guys who don't really get to train with someone who can evaluate their technique. If the person on the dvd is explaining the technique in detail as well as why they're doing it that way I would think that would make self-study much more productive.
Plus I'm really biased and I wanna see him blow up to international fame and fortune.
