That's impossible for the moment, X isn't implemented in the same way that
MacOS X is.
OSX uses layers for each window so it can get the pixel content of that
window even if another
window is ontop. X11 is not like this. I thought to implement true
transparency myself a few
weeks ago but dropped the project very soon.

So, if you want true transparent you would have to rewrite lots of the X11
code too.

Too bad, :(
