You mean a back-end? ;) Actually, lots of us around here run Myth  
systems that are headless. However, the majority of us prefer to use  
command-line interactions over SSH instead. For the most part, this  
is kind of off-topic, and you might find more help looking up a  
mailing list for X11VNC, or checking out their help documentation,  
but I'll help with what little expertise I can offer.

I'm not sure you can. X11VNC requires a running instance of X11 to  
manipulate, which, in turn, requires a user to be logged in. Of  
course, if you'd like to avoid that mess, consider just straight VNC.  
But, that would also require a user to activate it.

Go to the home directory of the user you plan to be using, and exit  
the .xinitrc file. It might also be known as .xsession
Insert the proper command to activate x11vnc. I'm no expert  
on .xsession files, but I'm sure you can find a straight forward  
guide somewhere on the net.

This basically says, if you don't know how to edit a .xsession file,  
see if your window manager (KDE, Gnome, Fluxbox, etc.) has a  
configuration option to run certain commands when you load up X11  
(kinda like Windows "startup" items)

That's an example command.
