It probably would be a bit better to send this to gtk-devel-list.

Hmmm, this seems like it could go on forever. GTK_TARGET_SAME_GRANDPARENT?

Unless SAME_PARENT is more generally useful than I think, I think it
might be best to just supply your own drag_motion handler that uses
gtk_drag_get_widget(). The one change to GTK+ that might be nice in
this case is to make some equivalent of gtk_drag_dest_find_target
public() to make writing a drag_motion handler a bit easier.
