OpenBSD Journal has posted a summary of Slackathon 2009, an OpenBSD conference.  You can find article at http://undeadly.org/cgi?action=article&sid=20090915071153.  Included are links to videos (raw and Youtube) of some of the discussions.
(On a side note, I’ve always wondered why Slackware Linux didn’t grab the name “Slackathon”.)
