Yes, this is possible, by writing a driver that provides the 'map'  
interface.  When the map is updated, publish a map info data message  
(subtype PLAYER_MAP_DATA_INFO) with the metadata for the new map.   
Then subscribers know that they should re-request the map.  Not many  
parts of player will do the re-request automatically, so other  
enhancements may be necessary, depending on which planner, etc.,  
you're using.
