Any open source widgets like this one?

Hi there,

We’ve been trying out a Flash widget on our side to serve up audio files for playback. It’s on box.net and you can see it on the left side of the page here:

http://box.net/widget

It works great, but I’m not super high on having their widget on our side. I’m guessing this may not be super complicated to do (but I might be wrong). Are there open source widgets like this out there that I can modify? Is something like this hard to build?

Any ideas or suggestions are appreciated. Thanks!

Tom
