Oh, thanx for the advices and offer from technik at piratenpartei-nrw.de!

Maybe I was a bit unclear, but I was more thinking something like.

1. "Me and the interview people" logs in to a mumble server, using
mumble client".

2. The admin of the server starts recording the "interview session"
somehow. (... and saves it to file we can use later. podcast,

3a. The sound is at the same time being sent to a software of some
kind (Maybe vlc?) that...
   3.b ... broadcasts the interview sound on the web via a link. (
Maybe there is some other software that needs to help here to do just
that - broadcast. )

4. The listeners access the link and starts listening.

The "link" is probably important to make available as part of the
"marketing" of the interview, so that is why this technicality needs
to be sorted as soon as possible.

If anyone can offer me a test where I can log in, say a few words and
get that sound broadcasted on the internet. Thats what I need. The
amount of listeners needs to be "large"... But I settle for anything.
