Been reading up lately on Display Link. It's basically video over USB and wireless USB in a semi-nutshell. An amalgam of manufacturers have jumped on board, producing everything from LG's usb-based display to things like Gefen's USB to DVI widget.
DisplayLink devices can even support internal grid/display mapping capabilities. Curious to see where this lands in live production environments. How about a Mac Mini driving 4 additional displays? Maybe?
Haven't been able to find any real testimonials of people trying to push 30 fps 480 or even 720 content down these things though.
PS, my favorite, a 4.3" touchscreen display, goes for about 150 bucks. Yes, you too can turn your desk into the Space Shuttle cockpit with these things
