This is interesting, but I'm not sure how well it will work when there is already a method (SFIR http://www.mikeindustries.com/blog/sifr/) that works around this licensing issue completely.

I suppose it will really come down to pricing, but they're going to really need to cut into those expected royalties if this is going to fly. It'll be interesting to see if font designers are as pig headed as music labels, or if they can understand that a lessor percentage of a larger total is the better deal.
