[Flickr APIs] flash slideshow

  Hi people,

   Exploring some methods of the API, I have produced a very simple
slideshow application in Flash, it works fine locally on my machine,
but as soon as I upload it to my webserver to test, there seems to
have a problem retrieving the xml response. Is there actually some
security restriction regarding requests from other domains? Do I have
to ask Cal to add my server domain to the crossdomain policy file? Or
the crossdomain policy file is already open to everyone and I am
missing something? :(
   I am not using any method that requires user authentication, only
flickr.photosets.getPhotos so far...

Here are some test urls:
http://www.mamata.com.br/flickrtests/slideshow.swf?user_id=49503114626@N01&photoset_id=3913
http://www.mamata.com.br/flickrtests/slideshow.swf?user_id=12037949754@N01&photoset_id=3898

and here is the code I am using (it's very very draft, just a test):


//-------- slideshow.as -----\\

api_key = //my api key here
if(!photoset_id) photoset_id = "3913"
if(!user_id) user_id = "49503114626@N01"
flickr_method = "flickr.photosets.getPhotos" 
rest_url = 
"http://www.flickr.com/services/rest/?method="+flickr_method+"&api_key="+api_key+"&photoset_id="+photoset_id
nphotos = 0;
flickrXml = new XML()
flickrXml.ignoreWhite = true;
flickrXml.onLoad = function(success){
        if(success){
                var rsp = this.firstChild
                if (rsp.firstChild.nodeName == "photoset"){
                        var photoset = rsp.firstChild
                        var photos = []
                        photos[0] = photoset.attributes['primary'];
                        for(var photo=photoset.firstChild; photo != null ; 
photo =
photo.nextSibling){
                                photos.push(photo.attributes['id'])
                        }
                        nphotos = photos.length;
                        displayMsg(nphotos+" photos remaining...")
