I am not sure if I agree on this, do you have some more links or some other kind of documentation? Regards Thomas
For an open source mindmapping and presentation tool, check out VUE (http://vue.tufts.edu; @vueProject). It's my go-to presentation tool. From the site: "The Visual Understanding Environment (VUE) is an Open Source project based at Tufts University. The VUE project is focused on creating flexible tools for managing and integrating digital resources in support of teaching, learning and research. VUE provides a flexible visual environment for structuring, presenting, and sharing digital information. "
