[dwm] question related to dzen and tail

Hello everyone,
Yesterday i tried to display new messages which were written into a log file.
I tried it with dzen:

(tail -n 0 -f /home/michael/irclogs/im/*bitlbee.log; sleep 10) | dzen2
-bg darkred -fg grey80 -fn fixed -y 1009

But dzen stays at the top all the time, it would be perfect if it would
only appear if a new line was written into the file.

Any ideas how to achive this?

best regards,
Michael
