For the people who want to know how it works:
I have modified the browser to start an embedded web server. This web server is based on libmicrohttpd ( http://www.gnu.org/software/libmicrohttpd/
), and automatically extracts each requested file from the zip file and delivers it to the browser. The unzip part uses minizip ( http://www.winimage.com/zLibDll/minizip.html
The URLs look like this: http://127.0.0.1:7766/media/mmcblk0p...LES/index.html
It would be fairly easy to modify the browser to show files from other kinds of archives (it requires modifying only one function). I've seen a few requests for an offline Wikipedia browser. Does anyone know a good archive format for Wikipedia?
