Hey Nicolas,

For load test check the page http://www.icecast.org/loadtest1.php
Basically you can have as many listeners on a single server as your
bandwidth can handle if the servers are relatively new.

As of redundancy it depends on your setup. Eg. can you feed the servers
from the studio or something, or do you have to use relaying. Do you get
the signal from the studio or have an FM radio card in the machine and
get the signal from the air?

As for the stream for the listeners I would suggest DNS round robin, it
mostly makes it's job.
