Check out FairlyCertain (http://www.fairtutor.com/fairlycertain/) when you get a chance. It's a .NET A/B library that you can pretty much just drop into your project and start writing tests.

Unlike the Javascript libraries from Google and VisualWebsiteOptimizer, everything happens on the server so you don't suffer any performance, user experience or SEO issues. I've been using it in my stuff for a while now and it works quite well.
