Thank you, Eric, for reminding me why i started the Tb router business in
the first place.  Btw, did you get any routers which can do OC-192 _today_,
not in the brave new world?

Dragging a lot of fiber never was a problem (except for the Sprint's
capacity planners, but that is another story).   Routing them is (and, no,
you cannot replace it with L2 switching of TDM or WDM kind).  Even tag
switching breaks down at IXPs (where flows are de-aggregated).  The
explanation why it is so is provided in a paper i wrote few years ago:
