Podcasting

effective web ministry notes has an interesting entry on podcasting and its future.
I think this could be the next big thing.
How long will it be before churches begin podcasting services or Bible studies to shut-ins or people traveling?
How great would it be to be traveling with your family during the summer, take a break at a restaurant with Wi-Fi access, or even from your hotel room, and in the process download a podcast of your church's Sunday morning service for you and your family to listen to as you continue your travel down the road.
With former MTV VJ and podcast founder Adam Curry giving podcasting a huge push and Sirius Radio giving Curry a four hour program to push podcasting -- it's coming.
How will we as Christians take advantage of it and use it to further the Kingdom of Heaven?
What other ways do you see podcasting being used to present the gospel in new relevant ways?
I'm excited and hope I can be on the frontlines.
