Indeed the intention of JSONP is to counteract the same point of origin
restriction. Since anything in a script tag is eval'd, if it is wrapped
in a function call, you can do something with results from a non-same origin
server. Doing stuff from within gwt, you can simply strip the callback off
and it will be valid JSON that you can use with gwt.
