> You can achieve pretty much the same isolation as Wayland on X11 with cgroups and Xephyr.

Wait, you mean I could get something almost as good just by adding in two additional technologies to the mix? Amazing!

Adding just one application (Xephyr) is a whole lot easier than replacing X, though. It's probably worse for isolation, but it's also probably good enough.
