I was also wondering about that. With El Capitan there was the big 'root' change. I guess they probably didn't break setuid, so this might still work.

I'm not sure about xraru working or not. If vncviewer runs on OS X, maybe? It might actually be a convenient way to run X programs in general.

Although if I add in any logic for auto-scaling, it'll likely break on OS X. But it'd be even more important because of the crazy retina resolutions.

xhyve, by the way, is an awesome hypervisor for OS X. It's pretty light. Not raru-light, but as light as you can get for proper hardware virtualization.
