Thus far a way has not been discovered to use the blending mode on bone animated models and have it look correct. It would only look right in the default pose. When the guy raises his arms though, the shading wouldn't change.
Also there are limitations on using it for levels as the only lights that work with the method in that demo are directional lights, not point lights. You can fake point lights with directional lights on characters, but not on levels.
I went over this in detail in other threads on dot3 mapping here so I won't go into more detail here. Find those threads by searching for Dot 3 or dot3.
