I wonder if anyone has thought of starting a Github repo of a JS library that follows the pattern defined on the Karaoke Web Standards site? Could be a fun project. Using the plethora of HTML5 API's available, I wonder if you could get close to a working karaoke prototype using HTML5 audio and video API's?
