Geo Location on GglMps Plugin OR OTHER?

I'm seeing the google map add-on called Buddypress Profile Maps. Does this allow members current location to be seen on a map when they are logged in??

What I'm looking to achieve is to have one large map with all the members shown as dots, based on their current location in the city. If they move from this place, while still logged in, the dot on the map will move with them.

Is this possible?

Is this possible at all with Wordpress/Buddypress using any other plugins in the entire market?

Or is this something that would require a custom app to be built outside of wordpress altogether?
