Well, Scott, assuming you mean ethernet over fiber, then you've just said
that it's economically infeasible to deploy the physical layer of 
precisely the architecture you advocate.

I find these conflicting reports most conflicting.

As for "what problems are you trying to solve", I just itemized that.
