Hi
I have a few tweaks for you all if you like.
You can see how we implemented it at:

I would be happy to contribute to this project bobster as I am already manually tweaking our install currently.
I have merged all the YUI code together with vbulletin uses to save speed (this would pretty much always be manual edit) and I have added some css for a *loading* splash.
The loading splash still needs a little tweaking but it looks a lot better.
I also have a few ideas about SEO but tbh all I wouldnt worry to much if your feeding google sitemaps etc as no content wont be found.
