A little more than 11 years ago, one of the creators of Tor, and the current President of the Tor project, Roger Dingledine, gave a talk for the members of the Norwegian Unix User group (NUUG). A video of the talk was recorded, and today, thanks to the great help from David Noble, I finally was able to publish the video of the talk on Frikanalen, the Norwegian open channel TV station where NUUG currently publishes its talks. You can watch the live stream using a web browser with WebM support, or check out the recording on the video on demand page for the talk "Tor: Anonymous communication for the US Department of Defence...and you.".
Here is the video included for those of you using browsers with HTML video and Ogg Theora support:
I guess the gist of the talk can be summarised quite simply: If you want to help the military in USA (and everyone else), use Tor. :)
