Online broadcasts.

I used the program. I liked it a lot. I watched live streams of Heroes 3. Not for long, though – it gets boring quickly. I still haven't realized what benefit this program can bring. Perhaps only for a small group of people, during the final battles. The most interesting thing is to watch streams from online tournaments, but then the confidentiality of the game is violated. The player can see the opponent's moves. Is anything known about the viewing restrictions?
