Hey B-n-c,
You are pretty much spot on with everything you mentioned.
Apparently app.io had some setup w/ VMs running on lightweight hypervisors (https://macstadium.com/casestudies), but we found we didn't have to have all that overhead to run multiple simulators per machine.
And you're exactly right about the small piece of custom code to pass controls and send frames. We're big fans of socket.io - pretty powerful stuff!
Happy to answer follow-ups if we missed something.
