Awesome resources. We’re going to be doing a big event in October(ish) using Livestreaming via (streamofconsciousness.ca) who you spoke to. Indeed very exciting times to be creatively creating and exploring what’s possible.
Yep, I think your case is best suited for using Youtube Live. I believe you can set the stream to private/unlisted so that its not accessible on Youtube (if you want). So you could then embed the stream on a page on your site, thus making it gated (or not gated).
