A bit of digging into a property list file included with Apple’s latest build of iTunes, version 10.1, may give us a hint as to what Apple might introduce in the near future. The plist file in question makes reference to “iTunes Live Stream,” an unannounced service that could find itself at the center of Apple’s announcement tomorrow. There is currently no solid information in terms of what iTunes Live Streaming might entail, but speculation ranges from live streaming of television programming to live user-generated audio and video streams. While nothing is known for sure, iTunes Live Streaming will likely be one of the first new services to make use of the $1 billion data center Apple is currently building.
