agreed up to the last clause.  but my base concern is not
config problems, but rather intentional attacks on the routing
system.  not to deny that there are config problems, they're
rife and a major pita.  but i suspect that the most agregious
will be dealt with by direct approaches to the security issues,
e.g. ip address ownership, as-path intent, etc.
