“Sometimes it seems that the world has moved entirely to DSL,
cable, and other forms of high-speed networking. But the reality is
it hasn’t–most of the world is on dial-up, and even in the US the

role. For example, a business may not need high-speed access–and
can spend the money saved on hardworking, worthy employees. (Stop
laughing, it could happen.) Or dial-up can fill a special need,
such as for nightly batch uploads, for remote access, or for
