AS3 stream mp3 over mms://

Hi there,

Im using AS3 to load some rather complicated XML from microsoft sharepoint. In this XML i have some URL pointing to our colleges media server, running windows media services.

We are using mms as the protocol. Can flash access the mp3s over this protocol or do i need to bribe my sysadmins to enable streaming over http? Also as the files will be at a different sub domain will this cause any problems, if so what are my options?

My flash file will be at a location like this:
http://moss.mycollege.ac.uk/site/files/my.swf

my mp3s will be at a location like this:
mms://audio.mycollege.ac.uk/french/01.mp3

or over http like this:
http://audio.mycollege.ac.uk/french/01.mp3

Any help would be greatly appreciated

Andy
