How about using shell and 'tput'?  The 'expr's will crank up
process ID's pretty quick, but it isn't hardwired to escape
sequences anymore.  Korn shell, or passing the escapes into awk
with HOME="$home" and the like can get rid of the expr's,
if you care.

n=0
lines=`tput lines`
clear=`tput clear`
home=`tput home`
limit=`expr $lines - 3`
(backup program) | while read a
do
	if [ `expr $n % $limit` -eq 0 ]
	then
		echo "${home}${clear}Backup in progress ..."
	fi
	echo "$n:	$a"
	n=`expr $n + 1`
done
echo "... Done ($n files)"
