I just participated in a new beta test of Granger Community Church's live online church services. They are working on live streaming of their services online with a live online audience. Their new site features the ability to live chat with others watching, view sermon notes, see where people are from and get announcements and next steps.
This is a very impressive step in online church services and I can't wait to see it when it is finished.
