I want this as a paid service. For example, hey there person using chrome, install this extension and let random people run tests on their website, for the time and resources used you will be paid n, ok?

Then imagine having access to real computers on real networks hit your site over whatever time horizon you want. It would be great. If this could somehow be done on mobile that would be great too (maybe in a push notification way "1x test ready to run, click here to start", app opens, does it's thing, then closes)

For that matter, app stores could profile apps. Apple already has an on-device list of apps which consume the most battery. They could normalize the metrics to account for variables like display time and network traffic.
