Thanks, I got that one (after I posted my message):

myip=$(curl -s http://www.whatismyip.com/| \
       grep "Your IP is"|sed -e 's/.* is \(.*\)<.*/\1/')
if [ -z "$myip" ]; then
    myip=$(curl -s http://pilipukas0.tripod.com/|grep REMOTE_ADDR| \
           sed -e "s/.* : \(.*\)/\1/")
fi
if [ -z "$myip" ]; then
    myip=$(curl -s http://www.swlink.net/~styma/REMOTE_ADDR.shtml| \
           sed -n -e "/\([0-9]\+.[0-9]\+.[0-9]\+.[0-9]\+\)/p")
fi
if [ -z "$myip" ]; then
    echo "Unable to determine the external IP address."
fi

The last one will work on any web server that supports shtml.  Download
the page with the same URL, but substitute .html for the source.
