Well, it looks like a basic "cardio-belly"..."bellyrobic" class to me. Upbeat Arabic Pop blaring in the background, isolations performed at double speed...yep looks the same to me.
Not a novel idea in this neck of the woods, I'm not saying it's not fun...just not a new idea. She can actually patent the name Raqshobic because I doubt anyone would want to use it. The difficult part of combining bellydance with aerobic style activity is that the movement vocabulary is based on isolating muscle groups to create movement...that is not aerobic. The heart has to exceed and sustain a certain rate.

I'm afraid no matter what you call it, it's not going to fit the bill.
