[icecast] start-of-stream & end-of-stream detection

[Streamit]

I want to develop a script (preferably in PHP) to detect the following:
- if a stream is available (for example: http://www.streamit.nl/live)
- a stream has stopped

Has someone an idea if this is possible; if yes, how to do this?

Thanks,
Johan
