We need a simple flash swf file that will make an http call to an XML page, parse the page. The XML page will have a link to an MP3 file. The swf file should download the MP3 file, and hold it until another event says to play it. When the event says to play it, the swf file will play the MP3 file, then send back another http call to a file online and say that it played the file.
There is more to this, but this is the summary.
I need this done ASAP.
