While I don't mind the concept proposed, a few things immediately caught my eye: 1) How often are changes made to these CSS files? It seems to me that caching would be far more crucial than any marginal benefit of this practice. Also, what of allowing multiple CSS files to download in parallel via multiple <link> tags?

They're already gone. 3) Removing all whitespace makes the assumption that no whitespace is necessary. This will completely break, among other things, font-family: "Some Embedded Font";
