Security issues on Audio Stream

I’m writing a streaming audio player in flex for a client of mine. Everything is going fine except for the security issues.

I’m using computeSpectrum to draw a sound channel visualization and that function is one of the one’s flash security limits without proper use of a crossdomain file.

Basically its set up on two servers. www.clientswebsite.com/somedirectory/AudioPlayer.html is the page with my .swf.

streamstation.clientswebsite.com is a server with shoutcast set up. I had my client install IIS on port 80 so now theres a crossdomain file at streamstation.clientswebsite.com/crossdomain.xml.

The file is on the up and up:

[COLOR=#0000ff]<[/COLOR][COLOR=#990000]cross-domain-policy[/COLOR][COLOR=#0000ff]>[/COLOR]
[FONT=Courier New][COLOR=#ff0000] [/COLOR][/FONT] [COLOR=#0000ff]<[/COLOR][COLOR=#990000]site-control[/COLOR] [COLOR=#990000]permitted-cross-domain-policies[/COLOR][COLOR=#0000ff]="[/COLOR]master-only[COLOR=#0000ff]" />[/COLOR]

[FONT=Courier New][COLOR=#ff0000] [/COLOR][/FONT] [COLOR=#0000ff]<[/COLOR][COLOR=#990000]allow-access-from[/COLOR] [COLOR=#990000]domain[/COLOR][COLOR=#0000ff]="[/COLOR]*****[COLOR=#0000ff]" />[/COLOR]

[COLOR=#0000ff]</[/COLOR][COLOR=#990000]cross-domain-policy[/COLOR][COLOR=#0000ff]>[/COLOR]
[COLOR=#0000ff][/COLOR]
[COLOR=black]but for some reason I still get security issues poping up in my debug flash player.[/COLOR]

I am not at all a server or hardware guy, I’m a humble flash developer and this security issue has me stumped. So, I would greatly appreciate any advice you guys have.

Also, if its relevant, I’m developing this in Flex 3.

Any help at all would be greatly appreciated.
