I wasn't suggesting they charge for use of the design, I was suggesting they might actually sell the boards. It seems to be a missed opportunity if they wouldn't.
wbmw - IIRC, in many cases, particularly with high-end cards, nVidia doesn't allow any deviation from reference designs, except for minor things like upgraded coolers. They have the cards made(by Foxconn or MSI, I think?) and sell them to the AIB makers for relabeling.
