ok, you need:
a big fat pipe coming in
a method for people to reach you, so either dial up, or access to the street level telephone boxes that each households cable goes to
a method of distrbuting your big fat pipe to all of the people that have signed up, hardware and software
a means of billing them
a means of tracking usage
a means of hiring and paying your staff
a means of running your accounts
trained people to touch the telephone boxes or a really good relationship with state level telephone providers.
and thats just from guessing what they do, if you can't figure that out for yourself, don't touch it with a barge pole.
