Your own domain-specific Google apps

Google is offering apps (gmail, gcal, ...) for your domain.

Looks like if you have a registered domain name, instead of http://sandpipermontessori.googlepages.com, or mumblefrabitz@gmail.com, you can have your Googlepages web pages be http://sandpipermontessori.com and get gmail as your_name_here@mumblefrabitz.com.
