reliable connected clients count

[comboy]

Hi,

Thanks for great library! I love using it. I just have problem with one thing. How can I check how many clients are currently connected? There is this roster example and I can try count on subscribe/unsubscribe but these counters will be ruined if I restart juggernaut process (and even without it, my counting process dies and I'm lost forever). Is there any way to do this?

Thanks, Kacper
