Twitter-like applications for humanitarian relief operations

In "Humanitarian Twittermifan" (May 26th 2009) the Sahana Disaster Management System blog discusses the use of Twitter-like microblogs for humanitarian relief. The particular application mentioned is for the World Food Program internal communication. This is implemented using open source microblogging package Laconica for the server and Twhirl for the client.

ps: In "National Bushfire Warning System: Micro-blogging for emergencies" I suggested the use of Twitter-like systems for use in bushfires.
