I have a better(?) idea.

How about we make the whole site style-sheet compatible,
and have an option in user settings to specify a location & name for the stylesheet, that way everyone can personalize their own theme, without too much carp being added to the server.
How's this for clarification:
In user setting, where you specify what theme you want, you have an option to choose a style-sheet version of the site, with the option of specifying a location for the stylesheet.
