2nd renderwindow

hi folks, i'd like to open a new window from an application, in xna it was easy, is it possible in unity? (like rendering the same scene in a second window on a second camera) like here <a data-cke-saved-href="http://www.youtube.com/watch?v=dyw9i5hmgq8" href="http://www.youtube.com/watch?v=dyw9i5hmgq8">

 

you could use System.Process

 

? i want a second window in the same application, how system.process comes to this? i dont want to manipulate an other application
