Do you know what this should mean?

The server has no a priori notion which users are "online".

You may artificially define the term "session"
and then consider the number of session as representing
the number of online users.
If you do this and you use Zope sessions to implement your
notion of "session", then you can look at the "session_data_manager"
to find out how many sessions are available.

Same problem for authenticated users.
You see them coming (because they log in) but you do not see
them going. Thus, you do not know when they become offline...
