The search for a Tablet camera

I was hoping that the Veo Traveler for Pocket PC would work with my Tablet. After contacting their sales department I find out that no, it will not work. I have a flap over my USB connectors, so even if I did find something like the Paceblade camera I would have to bend back the cover. PC Card slot and CF slot are exposed, so I am trying to find a camera to attach there.
