This ViDo looks good in theory. But I fear that the USB 2.0 bandwith (~50MByte/s) is too low. The PCIe has a bandwith of ~500 MByte/s. If you need to copy a moderate amount of textures, around 400 MByte into the GPU's memory then you have a massive lag (8 sec instead of 0,8 sec).
USB 3.0 will not have that bottleneck, but USB 2.0 does at the moment.
