I don't think these implementations are comparable to what Google is doing.<br><br>These implementations require you to click a button and for a request to go back to the server and come back.<br><br>Google doesn't ever go back to the server, they (efficiently) send everything over on map/layer load and then are able to know when you hover over a feature/box.<br>
