The way the old cable system worked was like this:
+-----+ +--> rest of internet
|your | |
|box |---- router ---- firewall ---- web proxy cache
+-----+ | \---NNTP server
| \--- other local services
usage database
authentication database
and there were modified Guantlet proxies that did
billing on the firewall.
Of course, there's nothing to say that's what they do now.
