If this was going to be possible with Windows, it would have to be done by Redmond. And given that they'd be out of a Windows license by allowing containers w/in Windows (as opposed to VMs), I doubt that will happen.

Unless you're talking about running this as a Linux VM on a Windows host, in which case, sure - why not?

Maybe somebody can bring CoLinux up to 3.8. http://www.colinux.org/?section=status

Well, you can run a Linux VM. Windows doesn't support anything like BSD jails or LXC right now.

why? the less windows severs out there, the better.
