the advantage - as with switch stacking - is with administration.  You end
up with O(1) admin interfaces to lots of boxes instead of O(n).  This can
be important if there's too much overhead associated with maintaining
parallel installations of IOS and XR.

Personally, I'd be more concerned with the loss of path redundancy and loss
of service in the case of upgrades.
