A FOSS4G event can catalyse the geo community in the host country. Now is the time for Africa! Free and open source software in Sub-Saharan Africa is still in its infancy, but here is where the principles of FOSS4G can have the largest impact, in setting the FOSS4G agenda, together we can build the foundations for generations to come. FOSS4G Dar should be seen as a FOSS4G Africa, quite distinct from FOSS4G 2008 in Cape Town which because of its geography had a localised impact. Tanzania is accessible to much more of Africa as well as the Middle East and Arabian Peninsula and Indian subcontinent and so taps into a new 'impact zone' for OSGeo.
