I am not confused on the potential solutions.  I think there are just 
various solutions being provided.  So far I haven't seen a compelling 
reason to run X on the console.  Since that isn't a hard requirement, 
VNC seems to be the easiest solution.

Correct.  For X11, the "server" is the application that is actually 
doing the display of the X window system.  The computer running the 
application is the client.  This is a source of much confusion for people.

Correct.  It is running an X server, but it is not running on the 
console.  It doesn't connect to any real video device.

That is my understanding as well.

Edit /etc/sysconfig/vncservers.  Create a display name and user pair. 
Then turn on the vncserver service.  It is easier than configuring Xdm, 
GDM, etc and still doesn't require any Xorg.conf or the use of the local 
video card.
