Anyone ever worked on a "Presence System"?

I have an app that we're considering a "Presence System" for.

As I'm currently conceiving it, the JS Library will add a function to hit the DB, attaching it then to most UI events.

This should allow us to know the last time a user did something. The app will poll the server every $n seconds to see if it needs to update the visual portion of the UI with new data.

Is it really just that simple? Does anyone have any experience with the design of such? Potential pitfalls and quid-pro-quos? Security issues? Helpful bookmarks? 🙂

I keep last active time as part of the session management, since every request has to be validated into a session, I just make the session run an update when the session has been validated.

But, yes it is just that simple.

Thanks. So, even with AJAX, the session handles it all?

And I assume it's web only, no phone/VOIP stuff?
