Discussion Panels/Cage Fights

Think you need a challenge Greg? How about a panel discussion or just two guests trying to reconcile world views in a constructive, reasonable manner... Where is the common ground between Dubay and say... Jan Irvin. Can they put their heads together and find common ground?
I half wrote this just because I'd like to see some precious theories collide and the resulting fireworks, BUT also because it would be interesting to hear some corroboration between experts of different fields. Nothing beats the intimacy of a one on one interview, but it might nice to mix it up one rainy day. So to speak. And you're a good interviewer bro... but can you referee?
