We have our own CSS compiler of sorts, before I ever heard of SASS. I'm curious if this is the direction for Ext4?

Also, is there JS version of the SASS compiler that anyone knows about? I hate having an ever increasing cornucopia of language dependencies for a build environment for JS & CSS. Our current system has duplicate implementations of the CSS compiler in JS and PHP so I can do CSS editing either on the server or live in the browser (where, really, it belongs, no?).
