It's an interesting idea, but there are "USB video cards" out there.
They plug into your USB port, enumerate as a regular video card, and
have VGA output. Very simply way of adding duel head to any system.

Being only USB2 the screen updates are NOT as fast as a real video card,
but for something like a datasheet or email it's supposedly more then
enough.
