I think it would be good if we could setup the map plugin so that spot data could be located in a separate location... such as a different xml file or data node.
I've played around with trying a simple <includeurl ="spotdata.xml" /> within the googlemap plugin structure... but it looks like it's ignored.
The concept would allow large amounts of map data to be split up over different files and loaded as needed... similar in idea to being able to specify at what zoom levels a spot shows up at... but more friendly to large amounts of data... of course, this would mean we'd have to be able to "reload" the map plugin and specify the new spot data as needed.
