The application for DragonFly for Google Summer of Code 2009 is in! This URL should show a public version of the application.
http://socghop.appspot.com/org_app/show/google/gsoc2009/dragonflybsd There's more detailed parts to the application that I had to fill out; if anyone's interested in the rather tedious details, I can send them along. I've added a student page to the site, too: http://www.dragonflybsd.org/gsoc2009student/
