1) Alright then, my mistake on that part. But add-in cards COULD still be coming out soon (as opposed to having whole new motherboards to have this feature). That was my whole point: That the controller itself would work fine via PCIe so there's no reason they couldn't make add-in cards.

2) Thats unfortunate. But what is the requirement for a controller to be designated as "licensed"? Is there a physical proprietary chip that is required? Or can it be implemented with code and added to existing displayport products?
