I did find this video. I don't know if the guys is an "IP" expert or not, maybe someone else knows something about him?

Is this the ability to move the Dantien? if so, I would compare this to Rickson Gracie's video:

If these are comparable things, I don't think Rickson has "IP" (if he does I would love to hear about that). Rickson is very into his body, and using it as efficiently as possible, which includes good core use.
