Facebook (finally) allowed Java Script in FB applications outside of IFRAME http://wiki.developers.facebook.com/index.php/FBJS Among other things, I liked how elegantly they are creating namespaces separating different applications on the same page. Seems that it cold be a security hole here - it is possible to enumerate java functions on the page and "impersonate" user actions with another apps installed on the same page. Other than that - it's great that we can use JavaScript outside of the IFRAME sandbox.
