I wonder if a social network that gets in touch consumers that want to buy something from abroad and frequent flyers could become a successful business?
For instance, a German wants to buy some obscure Japanese brand and gets in touch with a frequent flyer to bring him that for a small fee?

Also a social network that gets in touch senders/receivers and frequent flyers, to send and receive things. Of course that would be a bit risky since we would need to trust that the package that someone hands in to us, frequent flyers, to give to someone at our destination is ok?

What do you think about making money out of your many sky-miles?
