LaTeX is widely used in Linguistics (which arguably fits the category you ask about), both because of its capacity to hand the formalism of the more technical side of things, and its capacity to handle effectively the font-demands of those doing less formal work on "exotic" languages, or using a lot of IPA. No one that has been introduced to LaTeX in my department (and our student association runs workshops for their colleagues) has ever reverted to Word (or any "word processing" solution). Some kind of change-tracking or version control is definitely required; I have not yet found a solution I'm satisfied with (but I'll try some of the suggestions here; MediaWiki, e.g., seems like it might be an excellent idea).
