Things to consider: - Could most of this data be input to OSM completely? - Can we contribue to OSM? - Can OSM tell you a "zone"? - Then this module would be reduced to setting statuses of zones and exits. - Can the status of the exits of a zone define the status of a zone? - At the moment we're using exit statuses and leaving the concept of zone statusing. Is it useful? - At least use OSM to run the backend - Will we have OSM on phones? - Is OSM directly comparable with Google Maps?
