i think within most big law firms, there may be an enormous team which reviews documents, but when it comes to drafting documents, even at the biggest firms those teams are relatively small. i helped draft a section of a 2000 page document and the whole document just consisted of separate word documents with subjects like "chapter 1 rev2 final 9-3-2009.doc" which are passed around via email. but since the teams are relatively small, there aren't that many versions floating around so that can do a passable, if sometimes irritating, job. there are some types of version control already out there which lawyers use, e.g., hummingbird dm. it's pretty lame and annoying to use which is why many lawyers i know just do what i describe above for version control. so bottom line: yes, it'd be useful, but it would have to be very easy to use otherwise people would just use marginally more annoying but in some ways much easier to use (don't have to learn how to do something new) methods.
