Sound interesting, so you have a custom python ('PyDia') plug-in to modify 
your initial diagram?

Again, maybe you can help us to improve the NEWS file linked in my original 
mail ( http://svn.gnome.org/svn/dia/trunk/NEWS ). The feature of 
influencing the initial shape size is 'hidden' in this paragraph:

  * Shapes can now have sub-shapes that can be scaled or not when the main
    shape is scaled.  Also, it is now possible to specify that shapes
    are created with their stated sizes.

Not sure if I understand. Why don't you simply use fit-to-page in your diagram?

Moving objects is certainly possible with PyDia.

This is not very specific but there is some work done on PyDia, from ChangeLog:

2007-10-07  Hans Breuer  <hans breuer org>

        * plug-ins/python/paper-info.[ch] plug-ins/python/diamodule.c
          plug-ins/python/Makefile.am plug-ins/python/makefile.msc : wrap
        PaperInfo and ...
        * plug-ins/python/imgmap.py : (new) .. use it to scale the
        html image map like most bitmap exporters do

To be continued ;-)
