Has anyone used the Google website optimizer to do A/B or Multivariate testing on dynamic generated pages by coldfusion?

I'm trying to start some A/B testing and such on my site, but am not sure how to paste in the javascript google gives before and after the coldfusion segments of code, and then also add in the variations to google.

If this isn't possible, does anyone know of any way to a/b test a coldfusion site and still get some nice reports, etc from the experiment? ideally free ways, but if none of those are available then if there is 3rd party software, etc that's paid then maybe that too?
