I wonder if there are security games to play with javascript. Have the CSS encrypted in some non-trivial way. Have the JS decrypt it after querying a server for a key. You could do the same with images, or a least their file names. The query could include a token associated with the machine that served the page, and only the correct tokens would get the correct key. Just a thought.
