[Icecast] noncopyrighted content

[David Mehler]

Hello,

I'm setting up an icecast server and i'd like for it to do something.
I am looking for publically available content or
noncopyrighted-nonpatonted content I can load on to the server and
stream without worrying about copyright violations.

Also, what are the current security recommendations and best practices
for icecast and to a lesser extent ices?

Thanks.
Dave.
