I have not installed x11vnc server yet, but answered my own question 
about X11 being installed on a base Ubuntu Server and it is or was 
installed by the mythtv install. So adding x11vnc would not be a storage 
burden.  The reason I care is my whole Ubuntu server is running off a 
Sandisk 16GB usb flash drive.  All my data storage is on 4 - 2TB hard 
drives.

I didn't find the ssh -XC to be any faster than -X alone. But it's good 
enough to run once every few month for maintenance of the BE.

Thanks,
Jim A
