cagraham writes "BitTorrent has released a new file format called Bundle into closed alpha-testing today, according to VentureBeat. The format allows artists to embed a paywall inside of their work, and then distribute the art for free over BitTorrent. When users open the work they can listen or view part it for free, and are then prompted to either pay a fee, turn over their email address, or perhaps share the work over social media, in order to see the rest. The new format may ease artists concerns about releasing work for free and having to hope for compensation in the future. Artists who have already signed on include Madonna, The Pixies, and author Tim Feriss."
