In an earlier thread, I explored the notion of digital ink (Allstream offering, with OEMs from MiCo and Anoto Group).  But the possibility of a future mass application centered on this concept is very intriguing. 

More specifically, I was thinking of using digital ink and a type of digital paper in a format for the mass media, namely newspapers.  Something along the lines of a paper that would be able to update itself on an hourly basis, everytime a subscriber would pass through a public WiFi hotspot that upon successfully verifying the subscription status, would upload the latest updates that would appear on the digital paper.

Could the idea fly?  There are many technology elements that are already in place today to enable such a solution to become a reality.  Certainly the idea itself already exists and was showcased in Tom Cruise's sci-fi futuristic thriller, Minority Report.
