Within the web app for courses I organize, I'd like students to be able to provide their Stack Overflow username, so that we can pull in their most recent and unanswered questions. This information is [already publicly available](http://stackoverflow.com/users/1/jeff-atwood?tab=questions&sort=newest), but I'd like to pull it in through an API and list them together, so that students can see what's being asked and answer each other's questions.
