The closest thing to this I've heard about is the sparse voxel octree raycasting technloogy. John Carmack has stated that he is experimenting with this technology for possible use in a future version of idTech. There is also an interesting discusion in this thread http://ompf.org/foru...t=904&hilit=svo. The main problem with these kinds of technology is dynamic geometry. The SVO techlology I referred to was to only be used for the static geometry. I watched the video you linked to and two more videos from the same guy and i didn't hear him say something about animation (did he?). Animation is vital to a really lifelike environment... But even for static geometry like buildings this kind of technology is interesting...
You can do animation with SVO data sets by using boundary objects and performing ray transformations at the boundary into the AABB space of the data set. This is quickly mentioned in Laine's Nvidia paper on SVO. It's not that dynamic geometry isn't possible, it's just that it's not researched much at all.
The Euclideon guys have videos showing off animation.

This guy claims to have done it.

so do I claim

still working on a show off with better assets with some million polys.
