I don't believe X11 provides any means for Clients to ask the server for any information about any window -- including the root window. That's why "Eterm" requires that your either use Enlightenment as your windows manager, or set the background with "Esetroot" if you want any level of transparency. This gives Eterm something to query to find out what pixels are where in the root window.

I can't seem to find any docs mentioning an API to allow arbitrary programs to query Enlightenment/Esetroot for the background info, but i didn't look too hard so that doesn't mean it doesn't exist.

You could allways write your own wrapper script for setting the background image (using xv, or what have you) and making a symlink to the last file used to set the background that your other scritps can allways refrence when they want to know what the background is.
