This really makes me sad. Mutation events gets you to IE9 but not 8, which means this cannot be used for enterprise apps. I'll start using it in personal projects though. Love the work.
Yeah the funny thing is I could actually even make it work in IE6 and 7 if I used Mutation for IE9 and then - ready your pitchforks and torches folks - proprietary CSS Behavior script ducks to avoid tomato. IE8 screwed the pooch in this regard - they removed CSS Behaviors but failed to implement anything that could be used to do the same sort of thing.
