Inspired by the simplicity and conciseness of the m0n0wall config file, I've been thinking about setting up something similar for Nexista. In Nexista, you can have one or two config files, a global, or a global and a local file. In the end, they get combined and the local overrides some of the settings in the global file. But what I'm thinking about now is the ability to edit the configuration file via a web interface - which is really what I like about the m0n0wall setup. It shouldn't be too difficult at all, a little XML stream writing here, a little parsing there... presto!
