OT trivia: The idea actually predates either monotone or git;
opencm (http://opencm.org/docs.html) was using a similiar technique
for VCS access control a year or two prior to monotone's first
release.
Note that I didn't say Monotone invented it. :-) Graydon Hoare of
Monotone got the idea from a friend of his who, as far as we know,
came up with it independently. I personally got it from Eric Hughes
who came up with it independently. I think OpenCM got it from the
Xanadu project who came up with it independently. :-)
