I don't think you'll get that to work, because various Python bits of
omniidl assume the C++ bits are available in the _omniidl module. On
Windows, _omniidl is built in to the executable, so it isn't available
to import by the normal Python interpreter.

If you want to do what you're talking about, you're going to have to
build omniidl as a separate extension by modifying the make rules.

Cheers,

Duncan.
