But on the more business-y level, this does seem interesting. Ideally, there's a big potential market for people bumming cigarettes , especially in crowded areas. But I see two major problems:
- In crowded areas, how do you identify who the seller/buyer is ? There's a contacting issue (maybe face pics could solve this).
- As mentioned by gedrap, you'd need a pretty big density for this. People aren't willing to cross town to get a cig like they would to pick up free cupboards.
Honestly, a better solution for this would probably be a sort of dispensary where you could just deposit cigs somewhere and people could buy them. Or just cut out the user-aspect, and make a single-cigarette dispensary. That would avoid quality problems. Unfortunately this solution isn't necessarily "interesting", but it's probably the most "correct".
