this is, in fact, a useful point. detecting and compensating for
asymmetric routing is difficult in a metric such as this, although
it's probably not impossible.

i would agree that our method of routing table analysis has

do feel that pain *still* haven't decided that preventing hijacking by
means of authenticating routes is something they're willing to pay
extra for. so, like everything else on the $5/mb/s gige-port
internet, we get what we pay for and the lowest common denominator is
more or less
nd for a while and
obviously aren't being implemented by anyone yet). so my comments are
more general.
