IPFS podcasting kind of does that. You host your RSS feed and MP3 on your website and submit it here and then its distributed across the nodes. 

You can also submit feeds here just to use it as a back up for shows. 

The node runners then pin the shows they want to host. You can even add a split to your podcast so that any PC 2.0 Boost you get go to the node runners. 👀
