Upcoming Open Source Conference Presentation

I’ve been working recently on a paper I’m presenting to a conference in February 2006 titled Implementing Open Source for Optimal Business Performance. I’ve got the final glossy brochure yesterday so I now have something to show everybody. View Here (Be warned it’s a little bright)
