Peter closed T156237: To auto update WebPageTest agents or not, that is the question as Declined.

I think like this: This doesn't work out of the box and it's a real hack to get it to work for Windows. In the new Linux version we probably just update the agent our self and deploy it on a server (with a static IP), so then it will not be an issue (except for updating Chrome/Firefox but let us focus on that later.

There's one more thing I want to try out before we close this and that is to see that the workflow works with MIT Proxy. If it works, we can use it, The next thing is to make another test to see how stable the metrics will be.
