Currently WVoidMF is in it's planning stages. When it's completed, it will be a system that will have .mfs.html pages processed by it. A new XML template system will be designed as to allow for plain html files to be viewable by themselves, just not valid HTML because of the extra tags from MFS.
My goal for WVoidMF is that each module for it will work in a way that each acts as a black box to each other. This means that an upgrade to one module will not break other modules using it (unless the API changed in a way that will break stuff, like how PHP5 broke some PHP4 sites)
