Just how many people you share with depends on how well the cable company
does its job. They don't run all the cables in the city to a central
point for video distribution -- it's done as a tree. The irreducible
minimum area of sharing is had by putting the head-end data equipment at
the lowest level of video amplifier, serving, I dunno, maybe a few
residential city blocks or one big building. It is possible for the data
equipment to be higher up in the tree, in which case the sharing is over a
larger area. Almost certainly, most of the cable companies planning data
services will start with the head ends fairly high up and move them down as
volume grows.
Bear in mind that what they are selling is high data rates. Their whole
stock in trade is that they are better than modems. They'll move the
equipment as far down as necessary to achieve that.
