I think he means you don't need to pay for ml.org/dyndns.org services. BIND does allow you to remotely update entries in the DNS if you send it the correctly formatted command.

Windows tries to do update the DNS if you've got the "Register this connection in the DNS" option checked. This is a real pain because it's checked by default and I get millions of attempts by peoples Windows 2K/XP installation. I happen to also maintain the servers for home.org and unfortunately people like to use it as a pretend domain for their local networks. *grrr*
