Even if you could run a fiber exactly parallel and straight on the 
neutrino path (drilling a verrrry deep tunnel :-)) then the speed in 
the fiber will be lower than c, due to the refraction index. So, in 
any case a synchronization system is needed, and it is not necessary 
to run a straight fiber.
