What do you mean by "dynamic relighting"? I'm saying that even a flat texture captured mesh+video texture like this has to be lit to each shot it is placed in. That means it is being 're-lit' and any process that does that would be usable for regular CG.

Also again, the BRDF/normals of a capture like this are going to be very course. Cloth, skin, hair, eyes, metallic bits etc aren't going to look right if they have too much screen space over time. Quick motion blurred action might be applicable and I could see similar techniques being useful for crowds.
