The problem there, as I at least alluded to in my previous posting is that,
unless you already _have_ the local exchange, there's no was at the
edge router level to log the "local" traffic vs the "remote" traffic --
you could only do it in a local exchange environment by virtue of the
fact that theexchange existed in the first palce, to give the locals a
place to exchange routing info.
