Yes, I gave a read to it but if I remember I think there was a piece that didn't perform up to the speed of the thunderbolt link making the whole solution run 1/4 speed.

The solution approach I think goes as back as when using the express card port on elitebooks

It would be incredible on the other hand to get this solutions as official products from vendors like nvidia or asus without the DIY (not because I'm against it but to push making use of this solutions officially will improve the state of the solutions).
