Hey Steve,
I use Xvnc on three Sun systems for 40 users with the -query option.
I use a script in /etc/rc2.d/ like S98vnc to call another script.
This script will run Xvnc with my options then when you click exit on the
CDE panel, CDE exits and the script reruns itself. (note I don't have an &
in this script, to make it wait for the user to click exit).
This gives me a new vnc server per user. Now I can use it stateless.
I think the best advantage of the -query option is it gives the dtlogin
screen and any user can log in with there permissions set properly. (just
like an exceed or other xclient software). Second best is that you can use
-query 10.10.10.10 to specify another system with
the xserver running and use vnc as a very thin X client for a machine
without
vncserver running locally. (not recommended for long term use but it works.)

My beef is that Xvnc behaves much different than other X servers in how it
handles the startup script. Most X servers will read the .xinitrc file or
whatever startup file is specified and exit once the script exits. This
allows you to run the window manager (whether it's mwm, twm, CDE, VUE/RX,
GNOME, KDE, etc...) in the foreground (i.e. without an &) as the last
command in the startup script. That way once you exit the window manager,
the script exits, and the X server knows it's time to shutdown.
Xvnc just runs the script and then continues running until you kill the
actual server. This is obviously the case since the window manager in the
xstartup file is run in the background (the xstartup file will complete
almost immediately) and the session stays running.
I haven't tried using Xvnc in a query mode, so I can't comment on how that
works. The only odd thing I've noticed with my setup is that every once in a
while (twice a month for 200+ daily users), I get a call to clean up a
session. The symptom is a grey screen (the Xvnc server is running, but no
clients are running) and the solution is simply to kill the Xvnc process. I
haven't been able to track down why all the user's X clients die, but the X
server stays running. It's a real minor nuisance considering that VNC saved
me $40,000 in Windows X server licenses. I plan on adding one extra check in
my slightly modified vncserver script to check for this case and fix it
automatically.
