For those in the Utah vicinity, and who want to see a cool presentation about python, wiimotes and lasers (or who really like MS products, since most sessions seem dedicated to that), my brother is presenting at Utah Code Camp. It should be a little cooler than the Pycon version, since some more stuff has been added.
Oh, and I guess there is one other python talk amidst the sea of MS technologies, Kevin Kubasik is talking about twill and lxml.
