Is it working on the client-side?

Thank you for your great contribution. This will make a great plus for project.

I'm new to rails and google maps. Concerned about google maps HTTP request limit which is 2500. As far as I know gmap4rails uses GoogleMaps Javascript API V3 which doesn't make a licencing problem if its run on client side(with javascript).
I want to ask about this application. It retrieves coordinates from the database and resolves them on google's server(I guess) so does this mean it makes a request to google's server and after 2500 requests it will exceed the limit?
