It's not possible with just the session data because web sessions aren't
stateful.  You only get them on a request, so the best you can do is
update a cache of recently seen users (using one of the /autohandler
callbacks, which are invoked by RT::Interface::Web::HandleRequest for
every request).  Your "Who is logged in now" then uses the recently seen
users to show "who accessed RT in the past X minutes" where X is
something appropriate for your usage like 5 or 30.
