Apple Set Top Box?
Apple's been on a bit of a buying spree... with various purchases centered around their Pro Video market. Moxi Digital would have been an departure... and a bit of a curiousity... Moxi Digital has their own version of the digital hub:
The Moxi MC is a set-top box design using the company's middleware, which runs between a modified version of the Linux operating system and interactive services, such as a digital video recorder, digital music jukebox, enhanced DVD playback as well as online capabilities including instant messaging, e-mail, Web browsing and chat.
Not a clear fit for Apple's (public) plans...
