+<p>The <a href="http://www.nuug.no/">Norwegian Unix User Group</a> is
+recording our montly presentation on video, and recently we have
+worked on improving the quality of the recordings by mixing the slides
+directly with the video stream. For this, we use the
+<a href="http://dvswitch.alioth.debian.org/">dvswitch</a> package from
+the Debian video team. As this require quite one computer per video
+source, and NUUG do not have enough laptops available, we need to
+borrow laptops. And to avoid having to install extra software on
+these borrwed laptops, I have wrapped up all the programs needed on a
+bootable USB stick. The software required is dvswitch with assosiated
+source, sink and mixer applications and
+<a href="http://www.kinodv.org/">dvgrab</a>. To allow this setup to
+work without any configuration, I've patched dvswitch to use
+<a href="http://www.avahi.org/">avahi</a> to connect the various parts
+together. And to allow us to use laptops without firewire plugs, I
+upgraded dvgrab to the one from Debian/unstable to get one that work
+with USB sources. We have not yet tested this setup in a production
+setup, but I hope it will work properly, and allow us to set up a
+video mixer in a very short time frame. We will need it for
+<a href="http://www.goopen.no/">Go Open 2009</a>.</p>

+USB image</a> is for a 1 GB memory stick, but can be used on any
+larger stick as well.</p>
