Not a blind person, but I've made plenty of tactile maps for clients before.
I've never found smart pens to be too useful (in this case, the Pen Friend), because of the need to add the dots and record each individual message. It was usually easier to add braille labels.
Most of the time, I was there with the map to explain what they are feeling and what it represents in the real world. From the sounds of it, you want to make a more automated experience, right?
