				 Well you can't because of the Same Origin Policy. Basically this means that
				 because the domain of the query and the domain of the hosted site are different,
				 then that could well be a cross-site scripting (XSS) attack. So, the workaround is to
				 do the call from a script tag so the JSON we get back is part of the document. 
				 But since we don't know what URL to hit yet, once we find out then we have to inject
				 a new script tag dynamically which the browser will run as soon as we append it.
				 To be honest I'm not 100% why Google use RESTful services and not JSON-RPC or somesuch,
				 which would be easier. Well, easier for me.'''))
