Make cross domain JSON calls in JQuery for JSON feeds that don't support JSONP. Using a Yahoo Pipe as a proxy, pass in the URI for your JSON feed from any domain, and grab the Pipe's JSONP proxy output into your page.

function cross_domain_JSON_call(url){

 $.getJSON(
   url,
   function(data) { myCallbackFunction(data.value.items[0]); }
