I'm writing a scriptLoader applet, runnning on $(document).ready(), which: a) checks if a script has been loaded and b) if not, loads it as needed. I think this will help some, and it's following along with the whole plugin registry idea.

I place all my scripts at the bottom of my pages, just before the closing body tag. I think it definitely helps to stop the vsistor clicking the back button as they can see the information they came for immediately whilst in the background the javascript is loading.
