I am trying to help my church set up a way to stream the Sunday sermon live to a building next to us through the LAN. It would be ideal if we could connect a firewire camera to our Mac and input the audio stream from the mixer and output it across the LAN to a media device of some kind that we could connect to a TV in another part of the building. I have been searching on the internet for a solution of some kind but am not turning up anything substantial yet. Obviously we are trying to do it as cheap as possible and aren't afraid of homegrown solutions if needed. We are just looking for somewhere to start. I found a couple articles about Quicktime Broadcaster, but it seems like all the articles (and the software) hasn't been updated in years, so it might be an abandoned technology.
