Ethernet is very limited to the distances and it uses as much as 4 twisted copper pairs! We have some very nice technologies like VDSL that can provide very high-speed links! The 4B5B line coding is not suitable for long distance/single pair copper!!
Fiber to the home is the future, but let's forget about ATM. Leave it to the carriers. We're all going to use IP over Sonet with QoS/MPLS capabilities.
