Google is so helpful

I noticed this as a FAQ on Gmail:

I am a network administrator, and need to disable Gmail's chat features on my network.

We understand that it's sometimes necessary to disable instant messaging services on a network. If you need to prevent Gmail users on your network from chatting, we suggest blocking DNS lookups to chatenabled.mail.google.com, by returning 127.0.0.1.

I think that's the nicest thing anyone's ever said to me. Seriously, here in the misuse prevention business, it's often quite a pain to block IM/file transfer programs on behalf of customers (since virtually all of them actively attempt to evade firewalls), and for Google to go out of their way to tell people how to block unwanted functionality just warms my heart.
