[BNM] Simple DNS question

[Graeme Sutherland]

What you are looking for is to get your users to set CNAME records in their
domain control panel.

For an implemenation of this in the real world, see how google apps allows
you to cname mail.mydomain.com to something.webapp.com.

Google apps does this using cnames.  Help here ->
