Sunstone logged-in users

how could I generate a list of users and ip adresses that are currently logged-in into sunstone?
could I get this out of sunstone.log?

Hi Jojo,

I did not find a regular way to do this either.
But I have a rough idea how you could do this:
The Sunstone server supports memcache as session storage. You could use memcache instead of memory (this requires the setup of a memcached) and then read the current sessions out of memcached.
Please be aware that an existing user session not necessarily means that the user is (still) active.

Hope this helps
