You'd have to use an RTMP address, which the Sound object
can't get to. I'm not sure if this is because of encoding problems
or simple because rtmp can't be accessed that way. Also, a lot of
the functionality of the SoundChannel object is lost (like any
attempt at visualization) when streaming through FMS.
I like how the LiveDocs list explicitly "stream through FMS"
as one of the options for the Sound object, but offer no
explanation of how to do so.
