Already had a look at that, too. "Unify" seems to not directly
implement any measure of redundancy. So if one Brick goes down,
everything that was there is gone. Maybe its possible to play with the
`mirror' translator as well, but on the first look, it seems to be
non-trivial to accomodate for a steady loss and addition of bricks.
