Feature request-don''t allow logout and exit

I am very happy with the launch of jive+spark on our terminal server + thin clients.

Now I notice that some users log off or even exit purposely so that no body bother them. This is a headache to the administrator as time is lost to get to them in other less effective method. Can we have a feature to put every user online whenever the thin client log on to the server and with no option to log out or exit. And also re-connect automatically if disconnected from jive?
