Two reasons, the main one being access control, the secondary one
being that we may want to have the two trees maintained by different
people in different places.

I don't think having two trees, keeping track of the differences, and
merging changes from one to another is a big problem.  I have this
Tk-based tool called `dirdiff' for visualizing the differences between
up to 5 trees.  If anyone wants to have a look at it, it's in
ftp://samba.anu.edu.au/pub/linux-pmac/misc/dirdiff.  It's still a
little rough around the edges and it doesn't have any documentation,
but it may be useful.
