Not currently, its a pretty simple feature. I think one could clone it and then extend it to add this functionality. There is not much to this feature if you look at the code.
I've got a plan to make a feature to plot site members/visitors on a map based on calculating approximate location from their ip address, just haven't had time for it. Every point has to be geocoded to a long and lat to show it on the map. The current feature passes the location to google first to geo code it then shows it on the map using long and lat. I think with a lot of locations this would be unwieldy and you would need to geocode ahead of time and store the long and lat in the db with the location info.
Best,
Joe
