I keep using smaart during nearly every show (I am a sound Engineer). It shows me valuable Data about what is happening in different Parts of the Audience. In Media business you sometimes have to run Presentations or videos for hours and want to prevent anybody from changing your system or accessing a private Computer the is used to show Powerpoint slides in a loop. When I lock my console I want to decide if it blacks out or keeps certain areas alive and viewable. ps: would be nice being able to customize the -LOCKED- message at password prompt like: "you can find me at the Bar, or at the toilet doing drugs. Do not let mew know that your touched my system. ;-)"
