Maybe it is a program to allow the listening of Dolby 5.1 as binaural audio for portable listening. Many movies now have the 5.1 track included for TV. If you could use spacial audio in a similar way to WaveArts's Panarama, you could have an amazing listening experience right at your desk for any movie!

At least I hope that's what it is. It could be presented to the system as a 5.1 capable sound device. That way, even DVD Player and Front Row could pass along the audio to it, translate, and move right into my head!
