FreeCast is a Java application which allows peer-to-peer streaming. It makes possible a stream broadcast to a large number of listeners from a simple DSL connection.

The FreeCast challenge is using the internet connection of each listener to provide the audio stream to the other listeners. This collaborative approach is helpful to avoid expensive and heavy network infrastructures needed by conventionnal network broadcasting applications.

Freecast can provide a way to a lot of small organizations to diffuse over Internet radio broadcasting, musical events, etc ... without a financial and technical dependency with a web hoster.

The theory didn't limit the listener count of a such network but in the real life, Internet is chaotic ... A FreeCast network needs to modify itself continuously to keep the quality of service. It's an hard technical challenge which should be transparent to the FreeCast users.
