"The importance is that the licenses are available, and things are moving forward." However, RealNetworks executives have remained hesitant in divulging specific details about the service. One of the biggest questions is whether MusicNet will support archrival Microsoft's Windows Media Audio technology for streaming and the secure downloading of music. Many of the major record labels have supported Microsoft's audio format, leaving the question open as to whether RealNetworks may be forced to adopt its enemy's technology. "We are not talking specifically about the other technology pieces," RealNetworks' Glaser said during a press conference, adding that more details will be revealed in the coming months. MusicNet will use RealNetworks' RealSystem iQ as its security backbone.
