Tomorrow (January 27, 2009) we’ll be continuing the Media Sprint 2009, at the Zivtech office in Philly. Our stated goals: document the heck out of the Media module, and get a new PHP Stream Wrapper ready for it. And afterwards, at 3:30 PM EST, we’ll meet with the Drupal Dojo to teach interested folks how to write their own!
