cocoa - How to use NSTask as root?

Question

In an application I'm making I need to run the following command as root (user will be prompted trice if they really want to, and they will be asked to unmount their drives) using NSTask:

/bin/rm -rf /
#Yes, really

The problem is that simply using Substitute User Do (sudo) doesn't work as the user needs to enter the password to the non-available stdin. I'd rather like to show the user the same window as you'd see when you click the lock in Preferences.app, like this (hopefully with a shorter password):

Can anyone help me with this? Thanks.

Check out STPrivilegedTask, an Objective-C wrapper class around AuthorizationExecuteWithPrivileges() with an NSTask-like interface.
