The techniques of DWDM and pure optical switching by means of VCSELS and other lasing semiconductor solutions will in short order filter down to solve last mile problems.

I am confused (but fascinated) by the above, and by your and Frank C's belief that FITL is a practical near-term last mile solution. When you say "optical switching by means of VCSELs", do you mean using tunable VCSLs? If so, I think there are serious power and tuning continuity problems yet to be solved, plus I don't know of anyone making surface-emitting lasers which operate at DWDM frequencies. Will the fiber in the local loop be operating at a different frequency than in the MAN and the long-haul?
