A/B Testing framework - anyone interested?

[Warner Onstine]

Hi all, I've been thinking about this for a while and recently ran
across this RoR plugin:
http://vanity.labnotes.org/

I was thinking I'd like to do this for Grails. We could possible use
http://www.grails.org/plugin/feature-flipper as a starting point for
the A/B testing framework.

If there are others interested in this that would be awesome!
