} With enough QoS thrown at a Metro Ethernet service could you come close to

With enough bandwidth (40Gb ethernet is here today, although 1Gb
will suffice for many purposes for now) and QOS you get a solutions
that is probably "good enough".

Even with ATM you would have to have a service agreement in order
to get the level of service that you want.

I agree, people should walk to Blockbuster and get some exercise.
:-> One of the great things about modern networking is that you can
communicate with anybody in the world at anytime in anyplace in
realtime (not to mention above the world, considering that NASA has
done TCP/IP up to the shuttle). You can also move large amounts of
data around the world at very high speeds. These are also the problems
with modern networking since it means that people sit in front of
computers all day instead of getting out and seeing other live beings
and getting exercise. Given, what's on your website, you probably do
get out and about and get lots of exercise; but, there are plenty of
people that don't.
