This looks like awesome work. Thanks for making it available. To make your life easier, I've just merged complex number support into PyCUDA proper. If you'd like pycudafft to be part of PyCUDA itself, we can discuss how that could happen. Otherwise, please let me know if there's anything you need from PyCUDA. Thanks again for your work, Andreas
