Betty works for Canada Red Cross and need to get the Red Cross location in Haiti connected to other aid groups in Haiti to help arrange complex logistics of things like what order various aid agencies are even going to use the limited resources of the runway at the airport. Rohan and Betty both use the AidNet web application for communicating and have cached copies using the HTML5 offline support on their computers or, if they can't get their computers into the country, can at least get copy in via USB key and find a local computer with a browser. Rohan sets up a wireless access point on the tallest thing he can find and managed to provide wireless coverage for many square miles. Betty connects to that and manages to call Rohan to coordinate and let Rohan know the location of RedCross so that

If Rohan can't figure out how to include a DNS resolver that is 
advertised via DHCP with some locally-resolvable names (and, if needed, 
a web landing page that has some basic info about what to configure and 
where to get help) then Rohan shouldn't be in charge of setting up the 
wireless access point.

This is of course the same argument we had years ago on the original 
p2psip list.
