Thanks for the clarification. In theory, it sounds like this should be possible. MediaLab displays what is going on for the .que or .exp file that it runs and to which participants respond. So if you want more than one person to see what happens when a particular person runs and responds to a MediaLab .que file, you will most likely need all the display devices showing what goes on with the single drive where the MediaLab.exe program resides.
In practice. you will most likely need to play around with how the computers and display devices are set up in your particular situation. For example, you could try hooking up multiple monitors to a single computer. You could also try screen sharing using software designed for that purpose.
