Wikipedia's article on Missional Communities talks of Mike Breen's work. I spent three days on Pawley's Island with Mike Breen, Steve Cockram and the 3D folks, taking part in a meeting of churches who are on this journey with 3D. This is the real deal. Churches are being planted across Europe using this model. While it is a tumultous shift for a traditional church to move in this direction, I think it is the most authentic discipleship model I have seen to date.
