The A/B Theme Testing Plugin is nice...but what about a multivariant testing plugin?

I just learned about this multivariant testing software that goes beyond a/b split testing by simultaneously trying several different variations. And then it "learns" what words, fonts, colors convert and shows those combinations more frequently, while still showing other variations once in a while in case another variation performs better still.

The only problem? It doesn't work on php pages.

It would be great to have something like this that works on WP and works with BP!

Any +1s?
