Is this a plugin?

Does anybody know if this is a plugin this person has on their blog under their flashplayer?
It enables you to hide/download the mp3 you add to the player?

Does anybody know? If so, can you share the link to download?
I’d appreciate it.

[Update]oops! Forgot the link! This is what I’m talking about: http://edwards.org/2006/03/04/anchor-steam-part-deux/ [Update]
Maybe it’s a plugin the guy did for himself?
Not sure.
