Ok, so as far as I understand we could do the following: On the Saros side, have a polling mechanism that retrieves the presence of all contacts in the list. Then I would wonder whether the XMPP server just answers the last known presence status or actively asks the user in question to send his/her presence. On the other hand, as Stefan said, it's the server's job to detect disconnects, not Saros'.
Is that correct?
