Dan has an express no-dice policy regarding videos.
As for other forms of dissemination, his training model is simply based on hands-on. Similar to Chris, I've never been asked, nor can I think of anyone in Hawaii who's been asked, not to openly discuss the training model or specific exercises therein. That also applies to what's been imparted here by Mike Sigman and Sam Chin.
FWIW, there are threads in this forum where people have explained some of Dan's exercises in good detail and this was while he was still a participating member here. It doesn't matter what you provide, some people will always hold out their hand and demand more.
