If you marked shadows and associated them with their source, could you then recover the light source(s) and be able to remove the baked shadows and recast them in real time?

Also, with the shiny objects, could you specify the material properties and have it "back out" the reflection such that the reflection was recomputed as you moved the shape around?

This is sorcery! This technology is awesome. If it's as user friendly as they make it looks, I could see a lot of application for that!

One application I can see is teaching people how to model objects in 3d. You could use this as the 3-dimensional analog to tracing and have tutorials where you first get good at tracing the model and then try to recreate it from scratch.

For example, I have only tried my hand at 3d modelling once or twice (and sucked at it enough to give up), but just watching this I feel like I could model vases and lamp posts with a bit of practice.

What I was thinking all along: "Oh come on! It can't be this perfect, show me where it fails." And they did! This is indeed magic. I'm so happy to live in this age, and be part of the "Sorcerers' Guild".

Yeah, I was thinking the same thing. Funny how them pointing out the failures of the product make it seem cooler (since it seems more real).
