i did something similar to this once. i came to the same conclusion as shipley: trying to have other people edit your nibs is madness.

i chose to solve it in a different way, though. i kept all my localized strings in my own simple text file, and did away with nibs altogether, preferring to build all views and windows and menus in code at runtime. probably wouldn't work so hot for really complicated user interfaces, but it worked for me.
