You can use 'loadPolicyFile' to load a crossdomain.xml file from an alternate url via http.
The loadPolicyFile method contains the ability to load over xmlsocket: urls and I imagine it might also support ftp: and https: urls as well. I have not tested this functionality but if it is using the base networking in the player it "might" work. Ok, testing with: One issue is that this will require a wide open ftp server for read operations flash.system.Security.loadPolicyFile( 'ftp://server/crossdomain.xml' ) System.security.loadPolicyFile("xmlsocket://socks.mysite.com:123"); mySocket.connect("socks.mysite.com", 456); More testing needed here. I do have a set of binary Socket servers coming in a blog post later this month. The examples contain 4 servers that I wrote for working with binary Socket. I personally think that this is one of the coolest parts of Flash Player 9. More to come...

I heard that it is possible to create the connection using "flash.system.Security" class. Is there is any way to connect to lower ports such as FTP or POP without posting an XML file, or python script on the remote server?
