Permissions in Remote Desktop?

[jojasary]

This may seem like a silly question, but is it possible to set Remote Desktop so that the user who is about to have their screen controlled be asked permission to do so? I know this is essentially explaining what screen sharing does, but I would like to get remote desktop for the ability to move files and scripts to a large amount of computers simultaneously.

Can you disable the view where the administrator can view all of the computers and what they are doing? I ask this because some users are editing sensitive information and the administrator should not be able to see their screens unless they ask first.

Thanks
