Thanks, that seems to definitely be interesting. It doesn't really work 
(it sees no packets), but from tcpdump I can see the TTL expired messages 
in from all the hops so it still helps me!

I gave Scapy a shot before this and it seems that it should be able to do 
what I want as well (thanks to the others who suggested it), but after 15 
minutes I hadn't figured out how to make it do what I want. I'm putting 
learning it on my "todo" list though, it seems extremely powerful.
