Update: Unfortunately for Facebook users in the US, Netflix has confirmed that its Facebook integration will only be available in Canada and Latin America initially, due to a US law that "creates some confusion over our ability to allow U.S. members to share what they watch." That doesn't apply to the music services, however, and you can get an idea how Spotify will work in the video after the break. Even TiVo's gotten in on the action, announcing new sharing buttons for its iPhone and iPad mobile apps, although there's no direct DVR integration mentioned yet.
