The experiment at HBCSE proved conclusively that capital costs are very low. Caveat upstream has to be cheap and profits would be near zero.
How scalable was that network? Capital costs are low for any small network, but opex is relatively high. Can you show me how it would scale upto a few thousand nodes?
The problem in ISPs isn't one of bandwidth (that becomes cheaper per unit as you buy more), it's one of getting a reliable internal network which scales cheaply.
