Hmmm... Anyone ever considered addressing this via some sort of log
passing protocol or somesuch?
This is something identified by Martin Hamilton in the IETF wrec working group's "Known Problems" document (draft-ietf-wrec-know-prob-02.txt) but which was identified as out of scope for the group. That said, the work being proposed in the content peering community ( identifies a need for something similar. As Scott said, there's also RFC2227, though that doesn't appear to have much support.
