I was told it was implemented when I called security a couple
of years ago, and then my other questions were met with "no comment".
"No comment" is the appropriate response to a stranger calling and
asking for security information, and doesn't imply any other answer,
and I am willing to accept that it is no longer implemented, but
somebody told me it was. I am willing to accept that the person I
spoke to misinterpreted my question.
That said, I don't think it's economical to want to tap an oc-X,
but being able to grab single sessions doesn't necessarily have to scale
if they aren't grabbing lots of them, and can access them relatively
close to their source. It's the same issues as running IDS's.
Lets say you have a an IDS load balancer sitting on a GigE span
port with a few sensors watching everything go by. If an alert is
triggered, a script is executed which goes out to the router closest
to the origin of the session and initiates the overlaid tunnel.

Well, one would assume that these features would be necessary for the
maintainance of a robust security policy and architecture
implementation. The value is the same value that you get from
regular IDS's, just with a new customer.
:Sure, or they could ask carriers to tap lines for them silently... in fact
:they can do that today with a court order.
Indeed, and building features for automating the initialization of
those taps into the network is not extrordinarily difficult. (I
retract my "profoundly simple" comment.) The cost of doing so is
another loss avoidance cost that would be integrated into the overhead
cost that we currently call security anyway.
Are you suggesting that there might be money to be made by someone
who offered to integrate this sort of surviellence architecture into
