The impression I get from the article and linked article is that you can attach one of these "Plugable" devices to one of your computer's USB ports, attach a monitor/keyboard/mouse to the Plugable device, and you have another user seat working off your computer.
Pretty much. The hardware is essentially a USB 2.0 hub with an embedded VGA card and audio stuff. The hardware bundles the video/keyboard/mouse/audio into one USB device which makes it easy for the software to sort out on its end.
I think it's pretty cool that we can now do video over a vanilla serial interface that just plugs right in. Thank you Ajay Bhatt and Intel.
I, for one, welcome our new Thin Client Overlords /.
