Damn! That is A LOT of posturing going on there. I still haven't heard anything to back it up. There are a TON of body weight WODs (as I don't want to be called unfair for dpoing the heavier ones that I like) out there that would work great for a challenge. In fact, I just did a few this week at the hotel... a nice tabata with handstands push-ups (you can mod them to regulars, if you like), double unders (you can do single jump roping, if yu prefer) and sit-ups. I had a nice burpee, push-up, squat WOD too. 
...and you are right about how common certs are, but my k-mart door prize has served me pretty well so far. It's kind of like basic DUSM school. It's what you make of it. There'll be plenty of POSes out there in a few years who were standing next to you in class.
