Making money isn't everything, sometimes is good to know you have done good. On the 24 March 2007, the Sahana disaster management system project received the Free Software Foundation's award for Social Benefit. I helped with the user interface, with a version for Indonesia and get a "Notable Mention" on the Sahana Phase II Leadership page, which is nice.
Sahana is up to version 2 and there is work going on to add more mapping functions and mobile features. After a visit by the Sahana team to Sir Tim Berners Lee (inventor of the Web), the W3C has taken an interest. The W3C might apply its semantic web expertise to disaster management.
