[ka-Map-users] quick question

ka-Map provides a function to plot point data over top of the map  
(addObjectGeo in kaMap.js).  Using this function, it is possible to  
create images and add them as overlays, then update the position in  
'real-time' without changing the map data underneath.

However, to build this kind of functionality requires a bit of an  
investment in time to understand some of how ka-Map works and some  
reasonable knowledge of javascript.  Its not for the faint of heart!!!
