I hacked root-tail to work with Nautilus, KDE, and
hopefully XFCE4's xfdesktop. I took the toon_root.c file from xpenguins and
:r'd it into root-tail.c. A few modifications later and I had a working root-tail for nautilus.
Download the tarball: root-tail-xpenguins.tar.gz or just root-tail.c. Here it is in HTML: root-tail.c.html.
