X on a Qube (or any other headless / remote machine) is tremendously 
useful when combined with a VNC server. Imagine a graphical, 
interactive version of nohup. Once you start a virtual desktop, you can 
disconnect from the machine and your jobs will continue to run. You can 
later reconnect and bring up your virtual desktop just as you left it. 
I never send actual X applications to a remote machine; they always 
display to the local virtual desktop. That desktop, however, is easily 
sent anywhere across a network. VNC runs over a single port, so it's 
easy to tunnel the connections over SSH using port forwarding. It's the 
networking version of crack.
