I tooted an idea a while back on an #ActivityPub federated #Podcasting app. Well I found a project called #PubCast. All there is is a Github page some code that doesn't actually work yet but I love the fact that it's being worked on.
Expanding on my idea, they should add support for #WebTorrent too. Wouldn't it be awesome if anyone could setup their own podcast site and then people could follow via the #Fediverse or #RSS and stream via webtorrent so a popular show doesn't bring down their site?
