MobileMe File Sharing with Airport Extreme and Time Capsule

"New versions of Apple's wireless base stations supporting USB shared hard drives -- AirPort Extreme and Time Capsule -- have gained remote file sharing features via MobileMe. A firmware update is also expected to extend the feature to previous-generation models."

This is supposed to be extended to existing Airport Extremes and Time Capsules (thank you!) with an upcoming firmware update. I wish there was some way they could do that for the ability to run parallel guest networks and to operate both 2.4 GHz and 5 GHZ networks at once. Those apparently are hardware based upgrades, not much a firmware upgrade will do to fix that unfortunately. .
