[support] [Internet Radio] FOSS tools to create call-in station?

[Alec Taylor]

Good Evening,

I'm looking for a FOSS tool which will allow me to host a call-in
radio-station on my website.

Here's an example of what I'm looking for: http://i56.tinypic.com/aafz4k.png

Do you know of a FOSS project which provides the above functionality,
in full or in part?

Thanks for all suggestions,

Alec Taylor
