I'll be presenting ctypes this Tuesday at PyGTA. We have considerably longer at PyGTA than I will at PyCon, so we'll be able to go into more depth than we will in Texas. We're going to look at when/where/why and try to get into some of the how, time permitting.

As usual, we'll meet at Linux Caffe at 6:30pm and start the presentation proper at 7:00pm.
