Did some additional research, and it turns out all the marker movements are done locally, so it doesn't affect the API usage and it doesn't generate any traffic because all actions are done locally. As long as you don't do any requests to the Geocoding or Google Maps static resources or so, all code is executed locally.
In addition, the API limits are only on map loads, as I get it from this page: http://code.google.com/apis/maps/faq.html#usagelimits -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
