No, it's all loaded when the page is first loaded. One of the
enhancements for the map I'd like is background updates, so you don't
have to refresh the whole page to update the map data.

I'm not sure exactly what you're suggesting. Javascript places lat/lon
points on Google's slippy map interface. This allows you to pan the
map and zoom, and javascript will fetch the tiles for the new area,
and move the Point to the appropriate new pixel coordinate for the
lat/lon.

The only way to do something like this server side would be rendering
an image, then rendering a new image every time they want to pan or
zoom a new area. This would not be a good experience.
