If you won't allow your Streamers to syndicate their livestreams and GET DISCOVERED, then you are just contemplating another walled garden, like twitch or youtube.

You say "I don't want to syndicate to other networks". Well...

1. Most Streamers want their videos to be as discoverable as possible.
2. Most Streamers are tired of walking on eggshells in the walled gardens.
3. Most Streamers would love to get multiple sources of income.

I know you want to focus on just Hive. I started out that way myself, since 2014 in fact (bitshares then steem then hive). I was one of Hive's biggest cheerleaders; Peerhub used to be called Hive-Tube. "So I mean, there is all that."

However, after chatting with HUNDREDS of Streamers I learned one thing in particular... They want to be discovered. The best way to help them achieve that is to blast their content out there for them in as many places as possible. It's like SEO on steroids.

The world doesn't need more walled gardens. That's been done over and over and look where it's gotten us. Censorship, shadow-bans, demonetization, account blocks, downvotes...

Best of luck to you though, I was just trying to enlighten you and save you a ton of time and money.
