Worked like a charm!

(Well, actually, 'traceroute' here on Sonic.net's shell system seems to be
set up to NOT do hostname lookups, but a quick "host $BEFORE" gave me what
I wanted.  And the server I'll actually be doing this on seems to have
'traceroute' set up to do lookups automatically, so "$BEFORE" contained the
magic hostname I was looking for!)

Sweet!
