How easy is it to use ICEcast?

Icecast is actually very simple to use. You can use free software like Winamp to broadcast, which can be installed on any internet-connected Windows computer. There are also solutions available for Apple and Linux users. You can also consider using tools such as Simplecast and SAM Broadcaster; these are more professional and 100% SHOUTcast compatible tools. See Icecast hosting.
