Re: google maps

I need to be able to pan and zoom, that's why I'm using Google Maps.

The solution I am thinking of is to prerender the map as a layer on the server,  The user can then add markers as needed.  Their delete operations, however, will not show up until they reload (not optimal, but I cannot think of any other way).

I have developed an application in GWT which allows users to visualize a large graph.  The application has a few requirements:

1.) Display about 5000 nodes & edges
2.) add or delete nodes/edges from the graph
3.) click nodes/edges on the graph & execute a custom callback function
4.) Provide a blank overlay behind the markers so it is not obvious that this is a Google Map


I built this using gwt-maps-v2, but it performs very slugglishly.  Load time is slow, the elements take a while to reappear on pan/zoom, and the blank background flickers on pan/zoom.  I have seen solutions for this using javascript such as GMarker and MarkerLIght.  

Is there anything similar for GWT?
