Total Immersion's D'Fusion technology

The following is an interesting (although poor quality) video demonstrating
augumented reality technology developed by a company named D'Fusion.

I ran into this video today while reading some of the speculation
surrounding what the Nintendo Wii might have up its sleeves.

I would love to hear what your thoughts are about the potential of this kind
of technology :)
