You guys are all forgetting that this fluorescent stuff is read-only.

Even dual-layer DVDs have to be mass-stamped. I don't think there's even a such thing as a DVD burner that will do dual-layer discs. As I understand it, the layers have to be mastered separately.

I think you're forgetting that this is an entirely new technology. I believe the article says that it doesn't really use a laser. They also planned things like wallet sized cards that hold the same amount as a dual layer DVD, and I'd think that these would be writeable.
