My goal is to have a triple monitor setup, each running a different OS (Linux, Windows and MacOS) and have mouse/keyboard sharing using something like Synergy as well as moving app windows from one to the other (i.e have Windows running a game and move that app's window to the Linux desktop).
The idea is that since I use all three systems, I might as well have a seamless integration between them. I am open to running all three systems on one really powerful device (Linux running VMs for macOS and Windows) and to having three independent PCs each with one OS.
I prefer Wayland over X11, but I can use X if it would have easier compatibility for this type of thing. I have some minimal experience with programming so I can edit some configs and setup up a series of programs to make this work, but I can't completely create the entire thing from scratch.
Is this even possible? Maybe X11 Forwarding? Let me know what you guys suggest. I appreciate anything you have to offer.
