[Twisted-web] Copy livepage into div?

Hello, I have an XUL (intranet) application running from chrome and I would like to have a (athena) livepage in an (XUL) iframe. Not a problem you would say ... but those damn privileges prevent me from reaching the chrome from the livepage. A way to circumvent the privileges horror, is to load the remote html (via xmlhttpRequests) into for example a div on a (x)html page loaded from chrome. That works with simple pages (and scripts) ... but would it also work with a livepage and how should I tackle this problem? BTW: if anyone knows a method to enable all privileges for remote XUL (without bothering the user with dialogs asking for permission etc.) ... please let me know :-D Thanks... - Remi -
