This is what i was wondering. I have several TB of movies and about 10GB of music that is all stored on a custom built NAS in a 4u rack mount case. Storage my friend...anyway, this is what I(and my roommates) stream most of our movies/music from in the house. Other times, only for movies and music we don't yet have we use Pandora, Spotify, Netflix or Hulu. If it's only what comes from the ISP/Internet side then that's about 20%...if you want to count what is streamed internally as well, it's about 90%.
