I connected a linux box to a widescreen tv with vga and and used a $10 usb webcam on the linux box. Unfortunately they couldn't quite read their magazines comfortabley holding the usb camera. Depth of view and resolution were the problem. I read it's all in the software, so maybe dedicated drivers and a good camera are the way to go. What do you geeks think?"
