San Francisco - BitTorrent, the company launched by the creators of the popular peer-to-peer file-sharing application, on Tuesday announced the launch of a service that will use its technology to speed the delivery of streaming video, downloadable software and video games. The company says its BitTorrent Delivery Network Accelerator  (DNA) service can shift as much as 80% of content delivery to a secure, managed peer network. San Francisco-based BitTorrent said the first customer of the new service is Brightcove, a distributor of Internet TV channels for partners including AOL Video, Yahoo, CBS and Warner Music.
