Radio Statler (the hotel hosting the conference used to be called The Statler) will be broadcasting from radio.hope.net. The station will be live from 10 a.m. ET Friday until the close of the conference at 8 p.m. on Sunday.
There isn't a published schedule, most likely because there isn't an unpublished one, either. Plans are to stream the keynote presentations and other popular seminars, interview some of the speakers, carry reports from roving reporters, and talk to some of the attendees.
Hackers with their own podcasts are also invited to contribute. With a project manager named "LexIcon" a chief engineer who goes by "nikgod," it should be interesting. I'll be there, and maybe they'll even have a few minutes to talk to me.

Update July 18, 2008: There are two radio stations at The Last Hope. W2H (according to Bernie S., those are real, albeit temporary, call letters) is a ham radio station.
