This is incorrect, this isn't implemented, its not implementable, current
routing gear doesn't gre tunnel a) fast enough, b) at all.... HOWEVER,
juniper will allow you to copy packets on an interface in 5.5 or perhaps a
bit later code, this is one way to implement this... however having a new
oc-X for each oc-X you wanna monitor. I wonder if there is a limit to the
amount of fiber the OCS/NCS/NPIC wants to monitor?

even if the gre tunnel (Center Track (c) Robert Stone, et al.) idea worked
right and scaled correctly things would still be 'expensive'... to
monitor/maintain/manage.

Sure, or they could ask carriers to tap lines for them silently... in fact
they can do that today with a court order.
