_And_ a crystal ball to anticipate uncoordinated future changes by different 
parties in a single namespace and file tree.  The only ways this can be solved 
is to either have a single repository where nothing is excluded by policy and 
names and files are coordinated, or to delegate out package and file namespace 
to repositories that can't coordinate to keep them from conflicting.  Neither of 
these seem very likely to happen.
