Hmmm ... 

Excuse me if my ideas are kinda daft, but I don't know as much about the issues
as you do.

Would it be possible to simulate transparency by monitoring the root window
using gdk or xlib? As the background pixmaps changes, change the
pseudo-root-window pixmap? AFAIK, that's how transparent xterms work don't they?

And yes -- I realise that it won't be easy. I am just trying to figure out a way
of getting third party background tools to work with xfdesktop.

Of course, I don't know whether the benefit merits the kind of work involved.
