I wonder if it's possible to run a linux vm (ala jslinux) in browser, connect them to the network via a proxy to allow the apps inside the linux vm to make arbitrary connections (I think I saw a jslinux clone that uses some form of proxy to allow tcp access from inside the vm, but forgot the name), then run a kubernetes worker node in them. Then you can try to make the page viral somehow and then enjoy your huge and free kubernetes cluster!
I have a sinking suspicion that Facebook's Messenger webapp is doing exactly that - its UI has been very laggy for me in the past months, and the issue persists through refreshes, browser reboots and system reboots.
It's the only thing that makes sense. I mean, they couldn't have screwed up a chat client that badly...
