Stream of Gifts

The Dobe !Kung are a native people with a cultural tradition of gift-giving that crosses normal familial/tribal lines. It is said to promote unity among separated groups. In this tradition the gift implies a return obligation, and so on, in a chain that never actually ends.

Can this morph into the modern... Suppose as the giver you are anonymous, and the gift is accompanied with a reusable laminated card, explaining the anonymous obligation implied. Who would you gift to start the stream? I think I would pick someone very grumpy, and get them something really nice.
