I agree with Larry that it makes more sense in most cases to talk about section locks for the scenario of multiple authors wanting to manipulate different parts of the document. If your locks are on byte ranges, then the semantics (as I understand them) seem pretty unpleasant: 1. In the simplest approach, you can't change the size of the locked range unless you lock from the start of the range to the end of the document (thus effectively locking most of the document if what you're modifying is near the beginning of the document). 2. In a more complex approach, you can't safely re-lock a range using the same start & end points once you release the lock, because the actual byte numbering of that content in the document may have changed as others have inserted or deleted bytes from their ranges. Section locking also has this problem, but in a milder form: the problem arises as sections are added and removed, which one would expect to be much less common than adding and removing bytes. People who have more experience with byte-locking systems should feel free to correct me on these points if I have misunderstood. --Mark
