[maemo-developers] [maemo-developers] How to lock a User in a Sandbox

[From: Benjamin Zeller]

Hello,

Hope someone can help me here.....
Is it possible to write a programm which i can use to lock a User in a 
Sandbox?
The User should only be able to use a few Programms, if someone want to 
use the full system he has to type
a password and quit the "sandbox".
Because of this the Programm needs to catch all Messages (the Home 
Button Message) to prevent unauthorised access to the full system.


How can i do this (catch the messages)?


sorry for my bad english....

greets Benjamin
