MobileMe's Back to My Mac feature used to be just for accessing files stored on a drive attached to a Mac. Now, Apple has added an option for using Back to My Mac to access a drive attached to or inside a Time Capsule, or attached to an 802.11n AirPort Extreme Base Station. So, for example, if you're in Australia, you should be able to access files on a Time Capsule in Brazil, assuming you've properly set up your account, password, and the Brazil-based Time Capsule's incoming Internet access. The new Time Capsule and AirPort Extreme models released earlier this week come with the feature, and the older Time Capsule model and older 802.11n AirPort Extremes will get this feature via a firmware update from Apple.
