Traceroute can also use source-routed packets, so that one can
attempt to examine the path that packets are taking on their way
back to you.

However, some systems don't report all the interfaces, etc.
Like the nss, that apparently only decrements ttl once, even though
it goes through lots of interfaces.  Record-route does appear to
capture most of the interface addresses.  However, record-route
is limited to 9 addresses!  A source-route, record route ping 
would be a nice thing to try.  Anyone got one?
