nice fantasy land you live in.

in the real world, i'm seeing as much as 32 E1 PRI's (960 lines) connected
by a single 2mbit internet circuit.

that may be crowded to some people on the list, but it is not unrealistic
in some regions.

the BIG question is does the ISP have the bankroll to get going, but that
is way off topic here.

the economics of building an ISP are different from region to region.
