looks like good stuff, submitting a free trial request.
The only drawback I see is that:
#1 I imagine that you'd have to charge a bit more for a membership in order to cover the cost of the 3d goggles which will have to go out to every member
#2 Because you need the physical goggles, it's not instant (the orgasm that the surfer is paying for, that is)... so unless it gets big to the point where a LOT Of surfers already have the goggles, it may be a harder sell.
but, hopefully the uniqueness of this idea would make up for (in conversions) what you would lose because of those drawbacks. I can imagine an entire network of sites all in the 3d, so people who already have the goggles can pick and choose what kind of content they want to get just like signing up for a normal paysite. Now that would be SLICK
