Thats not the problem. that is already working.. The Disconnect idl time. 

Same for me. We use this tool for support and users that working @home.

Like also the option Blank Guest Monitor for that group! 

So support can remote control and the users can see what is going on.

remote user @home van work and send a Blank Guest schreen.. When the disconnect auto lock it! (I have a special session group for home workers)

Yes.. This wil be great. I need it for our client.. Everyone need a meeting account
