I know from the Gimp developers that GEGL (new pipeline based, graphics library for Gimp) supports on demand loading of pixel areas, so there is no real limit on the size of the images. http://gegl.org/pygegl/ http://gegl.org/gallery/index.html (some xml examples, not python)
It's probably still beta, but looks promising. Gegl is already in included in all major linux distributions and pygegl will be soon.
