I think there's a great opportunity to take online classes to the masses without sacrificing the quality of a brick and mortar education. These classes don't need to be offered free, just cheap. If they charged $10 for the whole class (a steal really!) they'd make $1,000,000 a semester per class. That should pay for the bandwidth, and teacher, and material. Scale that to less niche classes, you have a real business! I'd personally pay $10 for a class, even if it did not qualify for credit.
