I've been listening to audio from the Acts29 Feb. 2005 bootcamp. Acts29 is the church planting network created by Mark Driscoll, pastor of Mars Hill Church in Seattle. This is really phenomenal stuff, and extremely helpful for those who aren't planting churches as well.
Mark Driscoll: The Leader/Living God's Commands & Planning/Strategy
UPDATE: More good news. Acts29 boot camp from 2004 is also online. (HT: Peter)
