Not that Open Source; this is the new radio show hosted by Chris Lydon.
The shows are webcast plus they had planned on podcasting but bandwidth problems are holding up the podcasts. (The mp3s were in place but download times ranged in the multiple hours. Dave Winer’s attempted download went for five hours with no success.)
Mr. Winer did manage to obtain the first show (he was interviewed) and has made it available to us all. Thanks, Dave.
