Thanx Felix :) In my spare time I'm working on a little script that can find sites that are actively running hive-tube and federating their content. Hopefully I can make that list of url's public in the next month or so, and that list will have to be public anyway so that the HiveCast mobile app (mentioned above) can sync with it too.

Right now though, we are finishing up the peertube server v5.0.1 upgrade. It has a ton of fixes, lib updates and things. So, by tuesday of next week (fingers crossed) this huge upgrade will be complete and their breaking changes updated.
