You cannot just use a remote object as if it was a gtk.gdk.Pixmap, they
are just two very different pieces of code.

My guess is that for doing this, you would need to get the Pixmap from
the X server to the client side (Pixbuf), serialize it somehow, and pass
it as a dbus.ByteArray or as a path to a temp file in disk (if that's
possible in Rainbow). The other side would need to create a Pixbuf from
it and send it to the server as a Pixmap.

This process is not only convoluted, but will be also quite slow.

Perhaps there is some way in X for two processes to share pixmaps, but I
don't know about that.

Why you want to do that? If you explain it, perhaps we'll be able to
give better advice.
