As I posted in December last year, Apple have bought Proximity. The acquisition included a product named Artbox, which is one of the projects I worked on at Proximity. I have written most of the user interface for Artbox.
Apple are about to start shipping a new product called Final Cut Server, which is based on Artbox. There have been many changes under the hood, including a move to Apple's Compressor for transcoding, however the user interface appears to be substantially the same.
