Ok, so I bought a Dlink IP Camera. Then I added another hub to the network, so the DMZ consists of more than one machine. Stuff me if I then didn't port forward a couple of ports to the camera, so that if the wind is in the right direction, I haven't unplugged it, and you have a reasonably transparent Internet connection and the correct java plugin, you might see a video feed below. Otherwise, otherwise follow this link, and use the username 'view', password 'view'- this won't need the Java, but still won't work for everyone. I really wouldn't get too excited if I was you though.
