The simplest method is to issue a different gateway to a registry of known
offenders, forcing their into a restrictive environment that blocks all
ports, and uses network translation tricks to redirect all web traffic to
a portal.

For cable modems and bridged DSL, you can do this with DHCP, matching
their MAC address. PPPOE/DSL or similiar, you match on user name.
Issue RFC1918 space with a gateway to your quarantine network.

The rest is NAT/PAT and w3proxy stunts. You could pull it off with
something as simple as iptables and squid, after dealing with the DHCP or
authentication servers (ala Radius) to issue to the correct credentials.

yes, I could dream up a few hundred ways to accomplish this, but the
'documentation' at the site referenced doesn't address even one way. So,
saying 'it works' and 'it works for carriers' and 'yea us!' is not
helpful, without some example of 'how' :(

list of update sites.

there was little in the way of 'how' in the link above though :(
