I've been adding pieces to the UnitTest classes.
This addition tests embedding nested imports. The Python parts are in the tests directory and the managed parts are in the embed_tests directroy as are the nunit parts. This test also demonstrates some neat tricks that can be done when embedding a python interpreter in managed code by using reflection to call internal members of the Python.Runtime. The project settings file is VS2008, which means that it's probably time to go ahead and bring the rest of the project files up to a more recent version of Visual Studio.
