I hadn't seen that before, seems neat as the physical inconvenience factor of the KVM approach is definitely real.

It's pretty funny that you have both the input and output physically installed in and powered by the chassis, but then you run cables to connect them!

It would seem reasonable to at least have the option to have it directly enumerate as a USB hub/display device on the PCIe bus it gets power from! But maybe that would add a lot of bulk/cost?
