RealNetworks has announced Helix DRM, its digital rights management software that operates on both "Internet" and "standards-based" formats (i.e. RealAudio/Video as well as MPEG-4 and MP3, but not, of course, Windows Media). I wonder if Real waited to release this until the Intertrust patent issue was out of the way.
