I noticed on the free-track.org site under the webcams there is a reference that soon free-track will be available for use with the Nintendo WiiRemote. That means the WiiRemote will be used similar to the above, because the remote has a camera in it (a sturdy one at that).
Therefore, it should me 6DOF will be possible with a better camera.
So, in my case I'm going to drop in on freetrack every now and then.
The WiiRemote can be purchased pretty cheap off ebay and used

Also, I've not seen any discussion about the 3D rendering like the above with freetrack.
I get the idea that is more a Wii thing. It is awesome the way those circle project out of the screen.
