It is definitely possible, I am working on adding tranparency support
to the clockmail applet, well, it was working, but then I decided to
convert to gdk-pixbuf for all the graphics manipulations.. but now it
crashes, if only ElectricFence wasn't always catching a bug in the
gtk/gnome/popt init function somewhere (iconv) :(, I might be able to
make more progress.
This brings up two things:
A panel "do_draw" signal bug, here is the patch for applet-widget.c:

*rowstride = image->rowstride;
2) What is the best way to render a portion of one GdkPixbuf onto
another while applying the source's alpha channel? I made up my own
func, but is one already available, maybe in libart ?
