Traceroute supporting ICMP ECHO

Hi:
I'm using 4.7p1 here, and I've had all sorts of fun on occasion with
traceroute and my various firewall/routers. The default traceroute will
not work since UDP traffic is apparently blocked on the return. Opening up
port ranges on my router just doesn't seem right. However, Linux
traceroute has a -I option (I think Windows tracert uses ICMP ECHO by
default) which allows it to work through a home firewall router. The
FreeBSD port for mtr also works.
Is there anyone who has considered adding this capability to FreeBSD?
Thanks,
-Clint
