How can they do this without the go ahead from NV/AMD and all the chipset manufactures. This would require modding of chipset and graphics driver which are copy written. Seems odd there the only ones that are allowed to do this. I would think a company that used both brands of GPUs would get the green light first. Maybe there the first to come out with it and NV and AMD have open there hearts to the idea of sharing or it could be BS?
