AirPort Utility will be backwards compatible with Apple's previous generation AirPort Extreme and Express base stations. It will also add new features, such as the ability to monitor all connected clients on the AirPort wireless network -- an essential tool for businesses, schools, and other large wireless environments.
I am not interested in the new Airport, but I would love the long-overdue ability to monitor all connected clients on my current Airport Extreme. But where can I get just the new Airport Utility? I searched around the Apple website, but it appears you have to buy the new base station to get the new Airport Utility.
