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.

That's one of the hardest tasks to do properly on Mac OS X.

The guide documenting how to do this is the Authorization Services Programming Guide. There are multiple possibilities, as usual the most secure is the hardest to implement.

I've started writing a tool that uses a launchd daemon (the most secure way), the code is available on google code. So if you want, you can copy that code.
