yes i agree. really it depends on how robust you want the external CSS
sheet. if you are looking just to modify one or two properties, i definatly
would use dynamic JS or inline RAW css to be injected when the page is
rendered. ive found that using external css is great for defualt styles and
colors, then use inline css or inline JS to customize certain aspects of the
UI. This is great cuz you can set up some JS objects to represent your HTML
objects on the page, then easily set many styles, colors or images very
quickly and with a lil amount of code.

If the css styles you want to override can be stored in a string in
the ASO, you can just output that into the page as you would for
rendering the user's name on the screen. You don't _have_ to
regenerate the css code each time, and you only need to override the
parts that are user specific. I think people are doing this in T5 to
write custom javascript for AJAX functionality in their pages.

Sounds too expensive to me to generate the whole CSS dynamically. If you
just want to change the style for different applications, you can
override
the style in later style sheet; or, if you really want it dynamic, keep
the
link static but process it in servlet/service and serve up the image of
your
choice dynamically.
