I have had a quick look at the concept, to be followed up with a more thoughtful look when I have a bit of time.
I was involved with EDDUS in 1983 until cancelled. The son of EDDUS is working operationally in Europe. We always involved the controllers and some 70% of the new design was theirs. The radar data block used in Bretigny was developed from EDDUS.
Just one initial thought. The system may be better for the addition of variable translucent windows and the ability to directly address traffic underlying the active window.
