MX Simulator

I've been wondering if it is possible to do keycams in a spectator camera that you would see on stream. I figured it might be possible, but I really have no idea how you would go about doing it. Is it possible? If it isn't it would be a sick feature to have for content creators to have a kinda cable camera emulator.

It looks like they are enabled even when not playing a demo, but you'd have to be pretty lucky for the camera to actually be aimed at anything interesting since you'd have to know where the action is before it actually happens.
