Apple recently released a new firmware update (7.4.1) enabling Airport Extreme to connect to MobileMe. This should allow for remote access of connected storage devices. Enabling the feature is as easy as entering your MobileMe username and password under the "MobileMe" tab of the advanced features in the AirPort utility.Once enabled, your AirPort will be available under the "SHARED" collection in the Finder. You will likely have to click the "Connect As" button and enter your disk password if you have set one. Then all connected drives show up like they are local. Fantastic!
Assuming your home Internet connect stays up, you will always have access to your files. In my opinion, well worth the $99. Now files can be stored under your control and outside the cloud.
