You're right. I just tried it (not with the leap hardware) - the inability to "lift up" off the paper without leaving the sensor zone is weird. No haptic feedback when you're on the "paper" and not.

How about writing in the large - I am thinking big movements, like when writing on a marker board?

Still need to lift the marker to separate the words. And to touch it back rather precisely so not to have the next word to be an inch below the first one.

ain't feedback a relic of all 'press-double-hard-to-be-sure' buttons? With handwriting recognition it shouldn't be that hard. also, http://madebymany.com/blog/wizards-and-haptic-gestures

A Bluetooth 'dumb' stylus with a button or slide sensor could give a pretty convincing airbrush effect in a paint app.

I don't see traditional writing being a realistic application, though perhaps cursive signatures could work.
