Much of the Shepherds' Conference audio is already online. All of it will be posted soon. The MP3 downloads are free and can be accessed at the following link: https://www.shepherdsfellowship.org/MediaVault.aspx.
Note: You will need to login first as a Shepherds' Fellowship member. If you are not a member, you can sign up for free (at which point you will have access to all of the audio).
After you access the media vault (at the link above, or by clicking on the "Resources" tab), click on "Shepherds' Conference" and then on "2009" to access this year's audio. Pick what you want and download it to your computer.
On a side note, Lukas Van Dyke has been continually adding pictures of the conference to his website. Those pictures can be viewed here.
