I have a fully working mixin you can add to any loader which makes it lazy if you trigger the import on reading an attribute from the module: http://code.google.com/p/importers/source/browse/importers/lazy.py . But if you want to trigger the import on *writing* an attribute then I have yet to make that work in Python source (maybe people have an idea on how to make that work since __setattr__ doesn't mix well with __getattribute__).
