I like the concept — it could be enjoyable to have some of my long-distance friends playing together. However, people sometimes spoil things for others. It would create a lot of potential for collusion (players cooperating), so it’s probably not a wise idea. Even if a private key were required to join a table, Stake could likely detect and ban those accounts, but they might not. There’s already doubt about bots participating, and this would add more complications. Also, the high rake would ruin the fun when you’re just playing with friends.
