+Proof of concept patch for using kde's virtual workspaces from withing qemu,
+when running full screen (so that a virtual workspace is a whole OS).
+This should:
+- use configurable key bindings or even be able to get them from the current
+  environment
+- use dcop directly (preferably using runtime probing for dcop libs), without
+  having to invoke the dcop app (which is obviously slower)
+
+But for now whoever wants to can just hack in his key bindings and it will
+kind of work.
+
+Would actually be nice if kde (and gnome) had the ability to create workspaces
+on the fly, so qemu could have a mode when it assigns itself a completely new
+workspace on startup. This way I could have another OS running in the
+'background' without altering my workflow (that is -- without depriving me of
+one workspace which I normally use).
