Stream of what is playing in rhythmbox

Hi folks,

first of all thanks for the efforts you put in rhythmbox. I think its is a great software.

I would like to find out for which 'home setups' i can use rb. I guess that this question was asked before, but searching google and the mailing list archive i could not get a definitive answer.

Question: Are there (stable) ways to create an mp3-stream of what is currently playing in rhythmbox? Is there a plugin that supports this through icecast or something? Are there plans to add such support to rb?

Any hints on how to realize this are very welcome.

Thanks again,
