FEMA disaster website IE-only

As relief workers scramble to provide comfort and succor to the thousands and thousands of people dispossessed by hurricane Katrina, tech relief efforts are hitting snags. Equipment shortages, problems accessing the Internet, and the time it takes to set up computers for refugees to use are all getting in the way of getting people help, but that's not too surprising. This is, after all, a disaster.
What is surprising, however, is the fact that the Federal Emergency Management Agency's (FEMA) online registration site for disaster help is Internet Explorer-only.
Workers on the ground have told Ars Technica that they would prefer to avoid setting up Windows XP workstations because they take longer to setup, and even longer to properly patch and configure for use. You may recall that in an experiment performed last year, a Windows XP SP1 box put on the Internet was compromised in 4 minutes flat.
