Since you want to display results in an xterm, it means you have an X server running, so why not use Tk, Gtk2, Wx, etc. to do this? You could pop up windows with text boxes for the display, the 'q' key control would be easy, and you can setup timers. Nothing against POE, but did you choose it because you found some followtail code you thought you could modify? You can search groups.google.com for "perl tk tail file" for example code.
