i understand the usefulness of such a command, but is an applet
really necessary?  how about:

$ cat >macaddr <<\EOF
ifconfig $1 | sed -ne 's/.*HWaddr \(.*\)$/\1/p' -e q
EOF

or: 

$ cat >macaddr <<\EOF
set -- $(ip -o -f link address show $1)
echo ${11}
EOF

if you're requesting the mac address often enough that the
performance will make a difference, i'd love to hear more about
the application.
