Searching around I found Staco systems that manufactures a 8.4" touchscreen with tactile response when you touch a button on the screen. I have a link below.

I am thinking about purchasing one of these screens if a plugin can be made. Do you think it would be possible? I think this will be the way of the future with touch screens and be a great feature for centrafuse.
