PowerShell is an extremely powerful CLI. Windows Server 2012 (or whatever they end up calling it) is managed entirely through PS. Even the GUI is just an interface to PS. That means you can manage a WinSrv 2012 machine from any other machine, of any flavor. Looks like MS is finally playing major league ball, and playing it well.
I've been playing with that since it was Monad, and now do most of my work in a PS shell or the ISE. Anybody with a clue should have seen this coming when they put Jeffery Snover in charge of the Server division at MS.
