I have been digging juggernaut for a while now. It can be a bitch occasionally, but is a great solution! I use it for real-time monitoring of traffic on the site. It's working great still with 20 online users, broadcasting their clicks to an admin panel so I can see how users are interacting with the site in real-time. I am interested to see how it scales to 100+ users - my guess is in my particular example, the flash socket will give up much sooner than juggernaut itself!
