I think this is a fantastic model and would love to see it more widely used. For example, a small portion of the tuition of Stanford and MIT students (among others) finance the creation and publication of free quality education material to the rest of the world.

How much faster would our world develop if all education was made available this way, financed by people who have the money to spend to be the first to learn something/have the benefit of real-life interaction with the original professor?
