This looks great. I'm helping a friend with a site where this would be perfect for improving his conversions without as much work on my part.

One question though. Do the visitors get a cookie to maintain the split on return visits?

Yes, visitors get a cookie that has the value of the page they should see on return visits. For instance, if a visitor ends up on variation page #2, they will see variation page #2 from now on. Or at least until they reach the conversion page or the cookie expires in 30 days.
