In addition, Mark had talked briefly about revision control systems / bug reporting. Of course, he mentioned Canonical's Launchpad. Launchpad is most notably used with Ubuntu but it makes it possible to collaborate between free software projects, track new features/blueprints, and many other leading-edge features.
To this point though, Launchpad isn't available under a free software license aside from its Storm component. However, Mark Shuttleworth has stated this afternoon that within the next 12 months they expect to release the source-code to Launchpad. Beyond that, not many details were shed. Should we find out any other OSCON-generated details about Canonical's plans for opening up Launchpad, we'll post them, otherwise look for the source-code in probably 2009.
