Interesting topic. I don't think I've heard of this before.
While not specifically on topic.. there was a product used for balancing that was reviewed by Street Rodder Magazine. It's like sand or kitty litter that is poured into the tire and then you simply drive the vehicle and this stuff finds the location needed to even out the balance. It is used primarily for big truck tires, but it works well for car tires as well.

I know that wasn't the question but maybe the info could help.. Now we'll wait for others to share info on hub v lug centric rims. 8-)
