...but, at much closer look, quite useless. ;) Routers are there to *route*
packets, not to reply to ICMP queries. That is why ICMP processing is given
such a low priority (and not only by Cisco).

If somebody needs to measure their network characteristics *so* badly,
there's always Cisco SAA which seems to be part of almost everything Cisco
has nowdays that runs IOS (no, I didn't look at fn, because I'm stubborn and
lazy).
