I don't see the difference? Hierarchical or Peer delegation
policies between repositories are orthogonal choices to which
module system backs that repository.
It's precisely this orthogonality that causes me to think
that we can't just say "create a new repository implementation"
to change a particular rule/policy.
There are ~ N^2 choices of overrides to what the default
e.g. (probably not a good example since the osgi
module system would use OBR?)
1) A simple file repository containing jam files
2) The same containing osgi bundles
3) A remote repository containing jam files
4) A remote repository contains osgi bundles
And those are just two of the many
orthogonal choices 2^2 = 4
