Parallax Occlusion Mapping!?!?!

scroll down to…
Fig.25 on that page.

Is something like this possible for Blender 2.5 (and/or GE)

"Firstly, there’s parallax bump mapping (or virtual displacement mapping). Parallax mapping creates additional apparent depth by displacing the texture coordinates as a function of the viewing angle (Parallax Mapping).

Normal mapping has progressed to a point where, with parallax occlusion mapping, not only do we have a perturbed and parallax surface, but that surface is also self-occluding so that the texture casts shadows across it’s own surface"

It’s just Phenomenal, anyone know if this maybe coming to blender?

here is image of what I’m talking about.
