Sony and Blu-Ray pull a fast one -- free content!

According to an article over at T3, a leaked Sony document details a few secrets about the PS3 and its internal Blu-Ray player. The Playstation 3 will be one of Sony's first pieces of hardware to use the "BD Live" technology, which allows Blu-Ray players (not limited to the PS3 -- most Blu-Ray players will incorporate this technology given a year or two) to go online and download new content whenever a disc is inserted.

Thinking spyware? Adware? Pssh, please. Think more like movie trailers, actor biographies, or exclusive web-sites which can be accessed by the disc and/or saved directly onto your player for viewing later on. Sony says these downloadable contents can "also be shown, at least by the PS3, in a picture in picture window while the main movie is still playing." That doesn't seem really useful, but if you want to surf a secret website whilst a movie plays on, knock yourself out. Still, this downloadable content secret from Blu-Ray is pretty keen. Any ideas of good random content that will magically be downloaded onto your PS3? A movie soundtrack, at least a sample of, would be pretty cool.
