If you haven't checked out "The Mormon Channel" yet, it's well worth your time. There are lots of really interesting features on the site, all free, and most of which are available for download to listen to on an iPod or to burn to a CD.
Here are two of my favorites:
Conversations - this is a series of discussions with prominent church members and leaders.
Everything Creative - these are a series of conversations with people in a wide variety of backgrounds, talking about creativity and their process of solving problems creatively.
There is also a live streaming feature, which you can access by clicking on the yellow "Listen Now" button on the home page. There is also a free iPhone/iPod touch app available for download.
In addition, there are many other resources for parents and Church members. Just more proof we live in an amazing time.
