In the Googlemaps plugin (version => 2.12o) you can show the description of a placemark out of a KML file outside a map. The kml file has to be rendered with the GeoXML option. You need to add to the article a div with an id where you can want to place the information. For example: <div id='info'> </div> The id has to be place in the parameter kmlopendivmarkers to the {mosmap}.
