My local church as asked me to look into ways that we could possibly stream our church service with video and audio, as well as be able to access past recordings (archived for the last three recordings, if possible).
I am thinking about
www.UStream.tv , but I am not very familiar with their service.
The church has a fully set up sound system which could be plugged into the computer's input very easily (yall' could hear us sing, if you wanted to). We will look into USB-Based "webcam" cameras of slightly higher quality. (I am sure I will be searching for recommendations on that as well fairly soon).
