Skypecast RSS Feed

I need a script that when my Skypecast is going, the online Skype logo is showing on my website, and when the Skypecast is offline it will show the offline Skype logo. I am guessing this is RSS, but maybe its PHP. Thanks and I hope you can help me out.

I know of a PHP class that can do this for you, which is free...
