Nope.

You can use the DNASs XML statistics to gather the DNASs information then massage and output to your liking.

Check out the Sticky post titled...

Scroll down a bit and look for the section titled...
General SHOUTcast Information -> SHOUTcast ToolBox (All sorts of nifty add-ons for SHOUTcast)

1. The PHP based XML parser is a complete solution and comes ready for you to customize.

2. The Javascript parser (actually ASP) is another complete solution and comes ready for you to customize.
Note: Apparently this link isn't working anymore.
Try this thread for other ASP options.
