Google Maps Api Flash – Live Update Via Js

I’d like to have a map built using Google Maps API for Flash that can do the following

1) Display a map in flash
2) Add add an icon at a specified latitude and longitude via JavaScript.
3) Move map to location where flag is based on latitude/longitude

Here’s how it should work.
The map is displayed on the page. In JavaScript, we’ll have a function that can update the map with a new Latitude and longitude, the map should update as explained above.

I can show a live example of exactly what we want to qualified developers.

Thank you!
