I worked for a personalization vendor a few years ago and was on an engineering team that built a feature like this.  It was ... a major headache, and I don't think anyone was ever completely comfortable with the security implications.So I wish the team good luck, and especially with issues like:* A/B testing.  How can you ensure that what your clients are seeing is the same thing you are seeing?  Maybe you've been assigned to different A/B groups.* Extensions.  What if your clients are using Chrome extensions that affect how the page is rendered?  How can you replicate that?* Networking/auth issues.  What do you render if you're unable to connect or log in?
