Introduction
This page describes how to connect to a vncserver with opie. Everything ist tested with Siemens SIMpad SL4.
The advantage of VNC is that you are able to keep your session on the server if you are exiting. This means if you are anywhere and found a nice wireless spot you can connect to your server start an application type some text or do work and if you close the connection you will be able to reconnect with your desktop at home to the session and restart it where you stoped :). This also allows you to keep the session alive while your device goes to sleep.
Server
Create a session which fits your screen size e.g.
tightvncserver :66 -geometry 800x600 -depth 16 -name FOO
You may need to add a password. Have a deeper look at your distributions manual how to do it. (FIXME: add a good howto link or start describing it here)
Client
Install opie-keypebble.
If you want a secure connection - which is most users want you will need to create a tunnel.
At a terminal on your device do:
ssh -v -L 5966:localhost:5966 username@server
The port is calculated like this:
5900 + 66 from "tightvncserver :66"
Start Applications/VNC Viewer and change the connection settings:
Uncheck "Request 8-bit session" to have full 16 bit colors 
Enjoy your session
