Isn't this just view frustum culling?

No, it's occlusion culling (offline baked as far as I understand it).

It really reminds me of RAGE for the iPhone.

I may be understanding Seurat wrong but I think its more than just that. I think they bake a surface light field and do some form of image-based rendering against a much lower-poly version of the mesh.

Not really. The process takes RGB and depth images and regenerates a new mesh of the scene.

The process is able to reconstruct occluded objects by using multiple images from within a view box. That way the scene should look fully intact as long as the viewer is within the box.

Think stitching together a 3d panorama but with enough capture data that you can also peek around things.

It's great for performance enhancement but it seems like it would never work with global illumination.
