You seem to be assuming that the cable into your neighborhood is the same as 
the cable into your home, do you know that to be the case?

I believe it's ATM.  CO is connected to the "ATM cloud", ISP (istop, Bell, 
whoever) is also connected to ATM cloud.

Definitely.  Setting up a simple relay like all other ISPs must be beyond 
them, or perhaps they didn't realize that they could simultaneously setup 
anonymous relaying for their own IPs and authenticated relaying for remote 
connections ;-)

Agreed.  PPPoE doesn't present any barrier and with some actual competition in 
the DSL market bargains (like istop) are out there.
