strings is a great Linux tool. You run it and it burps up all of the coherent strings of text in a file. Even ran it against the new iTunes and found:

rental-content

rental-bag

rbsync

source-rental-info

dest-rental-info

Which seems to suggest some sort of video rental stuff coming up soon. It could also suggest some sort of vestigial functionality from iTunes 1.1 when Steve, during a Shamanistic hot lodge ritual, was offered a vision of a version of iTunes that could burn DVDs and then the iPods could fly out and destroy the DVDs after a certain period. Perhaps the world will never know.

Video Rentals Coming Soon to iTunes?
