Or xpra ("screen for X"), or NX, in which case you don't need to run
full screen.

I Would recommend Xvfb and x11vnc rather than Xvnc. 
Many X apps will not run on Xvnc since it does not support some newer X 
extensions. Especially Qt apps.

Here is an example script:
Xvfb :2 -screen 0 1015x690x24 &
sleep 6
# 
x11vnc -nevershared -display :2 -forever -passwdfile vncpasswd &
DISPLAY=:2
#export DISPLAY

sleep 3

DBUSLAUNCH=/usr/bin/dbus-launch
eval `$DBUSLAUNCH --sh-syntax --exit-with-session`

eval $(gnome-keyring-daemon --start --components=secrets)



 xfce4-panel &
#lxpanel --profile LXDE &
#sawfish &
openbox &
sleep 2

konsole &
#startkde &

while :; do 
sleep 20000
echo "tick"
done;
