Great project. For anyone interested in serving up static resources seamlessly, you can use something like the following in an Apache config:

  <IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteCond %{HTTP_USER_AGENT} !^CoralWebPrx
    RewriteRule "\.(png|jpg|css|js)$" http://%{HTTP_HOST}.nyud.net%{REQUEST_URI} [L]
  </IfModule>

I wonder if this can be used in any interesting ways as a drop-in performance enhancement. Using it as an automatic domain sharding solution might be viable?
