We've begun posting audio from last year's conference in podcast form . New recordings will be posted once or twice per week. The podcast is available in the iTunes Store podcast section , and you can also access the feed URLs directly. Three feeds are available: PyCon 2007 M4A feed -- smaller files; requires iTunes and/or an iPod. PyCon 2007 OGG feed -- mid-sized files; depends only on free software. PyCon 2007 MP3 feed -- larger files; compatible with most players.
