There was a hint of this suggested at the Beosound 5 premiere, in the form of future capabilities.
Building a Home Theatre PC at the moment, and the Media Centre One (XP or Win 7) allows the option to pull up and play any video file found on your computer, mouse or remote. I'm replacing the MCE remote with a Beo 4, via Lintronic.
Previously with Beoplayer, we had that ability if video files were store in N.PHOTO. It would be logical for B&O to provide that option for stored or downloaded video files.
