It's a matter of economies of scale. If everyone has to light their own 
fiber, you haven't saved that much.  If the fiber is lit, at L2, and 
charged back on a cost-recovery basis, then there are tremendous 
economies of scale.  The examples that come to mind are campus and 
corporate networks.

In theory, there is no difference between theory and practice.
