Thank you sooo much! :)
Whatever streaming platform you choose, make sure they do not require any KYC at all such as email or phone. KYC eventually leads to censorship. Also, streaming/social media platforms that have ads will also censor at some point, so try to avoid them.
https://Cast.Garden is a great podcast host too. Open RSS, P2P streams, no KYC or ads of course and unbeatable syndication.. even to the Fediverse network.
As long as the streaming platform offers media RSS feeds, and/or is powered by Hive-Tube on the back-end, the new HiveCast dapp will aggregate and tune in to it perfectly.
