The -once switch doesn't affect what happens when a VNC viewer connects or
disconnects.  To do what you want, you need to add code to quit the X server
in Xvnc/programs/Xserver/hw/vnc/rfbserver.c at then end of the function
rfbClientConnectionGone() - I think calling GiveUp() will do it.

However, what you're doing in some ways goes against the spirit of VNC.  One
of the benefits of VNC is avoiding the need to keep starting up and shutting
down applications and desktops.  In an ideal world you just have a single
desktop all the time and can use VNC to access it from wherever you are.

Cheers
