You already helped, thanks again. I'd just suggested to add a new feature to our main application, which would allow us to see, who is currently logged into the system. I also suggested to have ability to send message to everyone and kick them off after some grace period. My manager agreed, that this is a nice idea. So, we can ask our colleague to implement this feature.
