    I dont know how the Monastry is doing this, but if I had to implement it I would keep a last-activity timestamp in my database for all user sessions, and if a session has seen activity (i.e.: loaded a page from my site) in the last, say, 5 minutes, I would declare this a "currently online visitor".

      That's just what perlmonks does. Since HTTP isn't stateful, all we can do is know when you last hit a link/node on the site (logged in, of course). The other users lists shows everyone who did that in the last 3 minutes, updating every 3 minutes, which is why sometimes you can be chatting away on the CB, and not show up.

      C.
