The "xs" linker only allows you to load a GWT app from another origin
than the HTML host page; but you'll still face the SOP when doing RPC
and/or RequestBuilder, and you'll thus have to put some kind of proxy-
servlet at the same origin than the HTML host page to proxy requests
to the app engine application.
(I'm sure the GWT docs deal with this but I cannot find it... if only
they kept using docreader for the docs...)
