I would like to add the support letter [1] from IGP [2], the Portuguese Cartographic Institute. IVER, one of the leading company in the development of gvSIG, will send its letter soon too. Hope I'm not too late for this. best regards Lorenzo Becchi [1] http://www.ominiverdi.org/foss4g2010/supporting_letters/IGP.pdf [2] http://www.igeo.pt/
