The current display that is using the user is :0. And I want to connect to the
remote user, teach how to do some things and the user can't interact with her
desktop so the kbd/mouse input is blocked.
And about the display 0, I just know in linux the gemsvnc server to use the same
display without opening a new one.

That's not so easy, it has to be transparent for the user and the person that
wants to connect to the remote desktop. In the tightvnc one in Windows, when you
apply the change it notify the server but I can't automatize it. (I can't write
anything in the register and notify to the server without restarting the windows
In Linux I have no any option to do that and blocking the input is not posible
with X Window Programming because I have to interact with the VNC session.
