Nor I. So out of curiosity: how does this deal with the need to merge 
changes from others? So if for example I am a doc writer with access to 
docs/** and programmers have access to src/**, and I have a clone of 
yesterday's sources with some commits in docs and I run 'hg fetch' to 
pull and merge with today's changes in src, will I be allowed to push 
the merge changeset, even though it contains changes in src relative to 
the first parent? I guess there will be no new file revisions in src.
