So, no routers? How does the second ISP enter the business when the cable/fiber is already connected to the first ISP? Does the utility run 1000 cables/fiber strands in case 1000 ISPs join (and who pays for the other 999 if only one ISP joins the program or for tearing up the streets when the 1001st joins)?
Suppose, there ARE routers on a cable based system allowing multiple ISPs to share access to the same cable -- how do you deal with the case where one ISP's customers swamp the network? Who controls the the cable modems (I assume the utility would have to in order to control the shared cable resource) and, if there were no charge or caps for bandwidth, why wouldn't every ISP request the max possible speed and highest QoS config for each of their customers?
What am I missing here?
