I was just wondering if it is possible to use an external Ajax library like mootools, for example, or is the gadgets.io.makeRequest function our only option for making ajax calls from within our OS App. 

Thanks

There was a post about this a while ago but I can't find it anymore. I too am wondering what the allowed list is.

 I am using mootools for all my class structures and event handling and it works fine but when I try to make an Ajax request it just craps out.
