I'm making a Single Page Application which exists entirely inside the Namecoin network's name:value storage system. Values can only be a maximum size of one kilobyte, so the boot-strapping has to be very modular.
The root node contains a tiny Perl script which when executed on the command-line listens for incoming HTTP connections on port 2012. The request is treated as a requst for the content of a Namecoin node, but if there is no name specified, then a default node's content is returned.
If any nodes are requested they'll usually just be some JSON text defining the nodes DNS connections to other IP addresses or domains. The default node's content is however not JSON, but a small XHTML document. This loads a simple container page that loads some useful libraries such as jQuery and jQueryUI, and then requests any node specified in the hash fragment of the URL by Ajax.
