Another interesting software would be a PC application that shows in a window (with an update after every second) what it is seen in the screen of the DR1000S. This PC application that I think about should have a fullscreen mode. I do not have any idea if this is something difficult or not, or if this can be done by the already available Irex software.
I think this would be great (at least) for teachers. I can go to the lecture room with my Irex1000S and use a beamer for showing my slides to the attendance. And what it is more interesting, if at any moment I decide to create a new slide using the pen stylus I can automatically share it with all my students.
