As I said on the facebook thread, I don't think I'm much in the market for this, since I have way more listening-time than reading-time in my life right now.
THAT SAID: I could totally see myself paying for transcripts as a way to gather ideas for my own game. Some of Caleb's EP flavor elements from Know Evil or the plots from Tribes of Tokyo would be worth having in printed form so that I could incorporate them into my own games.
But as someone mentioned on Facebook, I'm not sure about possible IP legal problems. I know, for example, that Paizo has a somewhat complicated policy about what you can use their Golarion setting property for. Other companies might have similar-or-worse issues. You seem to be tight with Arc Dream and Posthuman Studios, so I imagine they'd probably be cool with things.
