A good idea, one I've had myself in the past. In addition to cameras, the port would be handy for microphones and wireless cards, or even active IR 3D scanners, a la HP Sprout or Leap Motion.
I believe some gamers use a head band and monitor-mounted sensor to allow them to look around the virtual cockpit of their starfighter.
The downside is mechanical - accidently bashing a usb dongle might have more dire consequences for a port mounted in a thin display than in a thick laptop chassis.
