Robert, no need for sshd on the client for this! LTSP5 has a whole
system for starting processes after X launches, but before the greeter.

There are in fact two different paths of interest in your chroot:

.../usr/share/ltsp/xinitrc.d/  (This is used for ANY graphical screen
script, ldm, rdesktop, etc)

.../usr/share/ldm/rc.d/ (This is used only for LDM)

If you create a script prefixed with the capital letter "I" (as in
"init"), this script will be *sourced* after X initializes but before
the greeter.

This is the ideal place to put a call to x11vnc.  Just make sure you
call x11vnc to die along with X, so it starts up every time and does not
daemonize or anything.

You will find other scripts in those directories as examples.  If you
are running an image-based distro, such as ubuntu, remember to update
the image after making changes.
