rendering a 360 Panorama (Cyclorama) to 8 screens

i want a window per player so I can move them (manually or using code) to different computer screens. And using a Multiplayer setup automatically does that for me.
I am sure you can render everything into one giant window and also render stereoscopically. It’s just not what I want. Also, you need an enormously powerful computer computer for that. I want one computer using two graphics cards to render each of the eight camera’s view to a separate window.
