So the thought is to set a max value for the IP TTL header in the outgoing packet? Cool idea. I have no idea how many platforms it's possible to implement that on from user level, though. Strikes me as something very interesting for diagnostics, but I'm not sure I would want to see it specified in the base Ping. Could be done as a ForwardingOption, however.
