This vs Remove NonViewable Menu items?

This module shows/hides menu items based on the role of the visitor. It does not control the accessibility of a page to which the menu may be pointing. So, even though the menu item may be hidden by this module, if a visitor types an address directly into their browser, they may still be able to reach the page.

Remove Non-Viewable Items shows/hides menu items based on the visitor's right to access the page to which the item is pointing. So, if the visitor has the right to view the page the menu points to, the menu will be shown - regardless of the role assigned to the visitor.

Both modules have advantages and limitations. The main limitation of *both* modules, is that neither one seems to have been updated to D6.
