I work very near the George Eastman House in Rochester and often enjoy lunch in their very pleasant cafe. Today it so happened that Kodak Alaris was holding a local employee conference at GEH and several participants were taking a break at a cafe table. Seated nearby, I couldn't help but overhear the topic of their animated conversation ... the development of marketing concepts to encourage cellphone and tablet users to print out their digital photos. I don't know if they were talking about photo kiosks or online services, but I certainly didn't hear any mention of film.
Probably a phone app, sadly, this already exists with infrastructure and print options already..
