Maybe I'm missing something, but:

- we are getting 10-20 km between repeaters on fiber links these days,
perhaps somewhat more with high clarity and laser transmitters.

- FDDI rings accomodate 512 nodes before we have to split the net.

- FDDI starts life at 100 Mbits.

Looks to me that 500 nodes times 20 km multiplies out to a pretty
decent regional backbone -- internet a half dozen of these and you've
got the country covered. Why are we fiddling around with ISDN?
