Jungo (http://jungo.com/), a company where I first learned the "proper" development process with code reviews etc, had instituted Vim as the company wide editor. You could choose something else if you still could work reasonably in vim and mastered that "other" editor to a high degree, being able to do x,y,z things with it. There was an actual document describing required level of mastery ;)

Now, vim being one of the top productive environments (only probably be contested by emacs), and the fact that we worked in C, so stags vim plugin provided as much IDE-ness you could get anywhere else at the time (2000), I think that was a very reasonable requirement. Eclipse? nah, not really, you can pry VIM from my dead hands, definitely would not work at this place.
