Yes, you understood everything correctly. This is my little project. I'm working on it. Its purpose is to listen to music in the office. It has a web interface and each employee can control the player. Player is connected to the loud sound of the dynamics, such that the entire department can hear. Everyone who has an appropriative karma can manage it, for example to upload their music and vote for someone else's tracks. I have already had to move this player on my work, but it requires good designers, and I not the best interface designers.
