I have a small project where I'll need to build a very minimal X11 environnement for a cyber coffee kind shop.

My idea is to have a simple server which will create a dozen of VNC Daemon listening on a different port (each port = one client).

The server is working, i can connect using vnc to different port.

Now i'm looking for a solution to create a customized desktop for each client; with a bare minimum of apps which i want to be able to add for each user. Like user1 will have app1 and app2, user2 will have app1 only etc.

I plan to use openbox as a WM but no clue on 'how' to add custom icons on the desktop of it.

Any clue, starting point would be interesting.
