When I saw this pie chart here it reminded me of the Open Source Governance that Ray Archer and I imagined when we started thinking about NewAthens (broken link). All we need to do is add sliders to each segment that would allow people to adjust the size of a segment, and a slider to adjust the total size of the pie. A wiki to collect data, debate and thoughts would be important too. Double clicking on a segment would allow citizens to drill down into more detailed charts of spending… well a man can dream.
