In fact, people were so interested that a few of us formed a group to further explore using Web 2.0 tools to connect people and resources in preparation for disaster.

I also met several mapping experts, including a guy who created real-time maps for the recent California wildfires. Very cool. There are a couple of nice write-ups about the conference on OSnews and DailyWireless.org.
