Wolfgang Kleinwächter asked me to write about "WSIS and the Software Challenge" for the UN ICT Task Force Series 8 (2005): "The World Summit on the Information Society — Moving from the Past into the Future"
It was edited by Daniel Stauffacher and Wolfgang Kleinwächter and has now come out with an opening statement by Kofi Annan, a preface by Yoshio Utsumi Edited by Daniel Stauffacher and Wolfgang Kleinwächter. You can go and pick up a copy at the booth of the UN ICT Task Force.
For those who just want to read the article, it is now online at http://fsfeurope.org/projects/wsis/wsis-and-software.en.html.
