public class CrossSiteIframeLinker
extends com.google.gwt.core.ext.linker.impl.SelectionScriptLinker

This linker uses an iframe to hold the code and a script tag to download the code. It can download code cross-site, because it uses a script tag to download it and because it never uses XHR. The iframe, meanwhile, makes it trivial to install additional code as the app runs.
