Navigation bar items based on logged in status..

Hi,
I’m currently running a site using the Mystique theme with a members only area. However, what I’d really like is to be able to change the navigation menu based on if a user is logged in or not. In other words, a user not logged in would see:

Home PrivateArea

as the navigation bar, while someone logged in might see

Home Page1 Page2 Page3

on their navigation bar.

I’ve found plugins that allow me to hide pages from the navigation bar, and plugins that allow me to make pages Members only, but is there a plugin that allows my navigation bar to show different pages based on logged in status?
