The problem with this model is obviously going to be producing the content and I'm surprised Gruber doesn't mention that. Distributing books this way will add a lot of complexity and cost to an already expensive workflow. If this format succeeds I imagine it will have more in common with "games" than it has with traditional "books". The model for funding and producing these "books" would therefor probably be more similar to how games are produced.
