Writing Decisions: Headline tests on the Highrise signup page

Quick story - a company I used to work for decided to A/B test their signup page. Everyone in the company could submit their "version" of the page. In the end, the best performer was the secretary, while the worst performer was the marketing guy.
One of the reasons I love trade shows. By the end of a few days talking to potential customers at a booth you'll have a rock solid pitch.

(We also paid a company that did optimization via Taguchi methods, and found them to be a bit of a scam.)
Besides this and Google Website Optimizer, I'd be curious if anyone on HN has used other AB or multivariate testing tools? I would absolutely love something open source that I could plug into Django templates on the server side, rather than depend on external Javascript code to rejigger the page.
The results of a follow-up after 30 days to see how many stay could also be enlightening.
