Essentially, all bandwidth is "shared" at some point.  Cable just starts
sharing it sooner (the "neighborhood ethernet" effect).  With DSL, you
get a dedicated connection at a particular speed to the CO, but once
there, you're aggregated with your ISP's other subscribers on the same
CO and sent out on a fatter pipe to whereever it goes from there.

To take an extreme example, everyone essentially accesses
ftp1.sourceforge.net through the same pipe, although you don't share the
connection until the last (few) hop(s).
