Yeah - VMware solved that by showing you a dialog with the remote file system. 
Pretty ugly.
Another solution to that would be to only enable the dialog box when target == 
localhost.

As soon as we look at server workloads, we do need to have network 
transparency. But I guess most of this talk is moot anyways, since we have VNC 
now. So if there is someone willing to take up on a GUI, he can just do so the 
same as he could with a unified backend.
