Such as this: http://labs.unitinteractive.com/unitpngfix.php I assume the CSS is loaded before the JavaScript and thus filters kick into effect, thus avoiding the bottleneck.

Some other oddities about the filters: When applying a filter in IE on an element with text, the fonts loses Cleartype anti-aliasing. Can look weird when animating opacity. Also, when using AlphaImageLoader on a link, the transparent area is sometimes no longer clickable. Nice post!
