This is aweesome! I've played around with the idea of building something like this in the past, and have always shied away because of the complexity. Well done - it looks super useful. One minor critique: Can you refer to yourself as "track.js" or "TrackJS" instead of {Track.js}? You're going to drive me nuts if I have to type curly braces every time I mention you somewhere.
