Ticket Service in the Cloud
Offer a service which relies on a huge stack of Amazon EC2 instances and unique IP’s to automatically hammer your ticket service of choice. You don’t have to break a sweat while the service gets you your tickets for that popular event.
The profit is in the little premium your clients pay for the tickets acquired through your service.
Mechanical Facebook
Create a Facebook app with minigames in which the user can win cheap stuff like badges or Facebook credit. The minigames are actually HITs pulled automatically from Amazon Mechanical Turk.
Profit is in the margin between the revenue from the HITs and the costs of the stuff you give away.
Bagel toppings
Make pieces of cheese and meats with a hole already stamped into them. Sell these toppings at a premium.
