Beast has been presented on a couple of conferences already. This is the place where we attempt to maintain a comprehensive list of online material available about the conferences:
Stefan Westerfeld attended the first LadConference 2003 and gave an overview of Beast. There are pictures of the event available and and OggVorbis? versions of the talks.
Tim Janik gave a presentation of Beast at LinuxTag 2003.
An online version of the accompanying paper is available here as a German Beast Overview.
