-<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>
