I've just posted a number of links to podcasts from Fuller Theological Seminary on my Links To Other Stuff page. (See the tab in the green bar at the top of this page.) There's all sorts of good stuff to be had including Graham Cray on Fresh Expressions, Darrell Guder on Missional Leadership After Christendom and Allan Roxburgh on contemporary mission. Go take a look.
I will stick up a few more links when I get round to it - I've particularly enjoyed listening to John Goldingay's Old Testament lectures - and I'll keep on adding stuff as I come across it. Keep on checking back from time to time just to make sure you don't miss out.
