Hide that, fade this in, add this event, etc.  But we want to work with another library, we don't need access to the DOM elements where we added our maps, we need access to the actual map object (OpenLayer or our own geojquery map objects).

But how do I interact with the map? $('#map') gives me a jQuery object where I can manipulate all attributes from the DOM object, but not the actual map. We can add the OpenLayers map or some geojQuery object as .data() to the element, but $('#map').data('map').center(lonlat) is rather quirky.
