My bad ... I don''t know why the heck I wrote port 80, I meant port 1024. (Too much apache configuration lately or something.) Anyway, you said you tried every conceivable crossdomain security configuration? Where are you serving the crossdomain.xml file from?
Note: A policy file served by an XMLSocket server has the same syntax as any other policy file, except that it must also specify the ports to which access is granted. When a policy file comes from a port lower than 1024, it can grant access to any ports; when a policy file comes from port 1024 or higher, it can grant access only to other ports 1024 and higher. The allowed ports are specified in a "to-ports" attribute in the <allow-access-from> tag.
