Just deny access to port 80 on their computers. But, they can always
change the port the server runs on. My experance has show that any port
filer can be worked around with a little work. WarFTPD even has an option
called "Fool my Brain Dead ISP" to switch the FTP server to another port.
What I do is any unusual usage gets a quick test with a port scanner to
see if any services in violation of our contract is running on the
customers box.
