Shared revenue of sponsored story promotions/snaps would be one way. Think of this: Create a marketplace around big businesses getting viral content producers to push their products subtly (Truman Show anyone?). Snapchat, acting as the intermediary and service provider, can collect a percentage of the promotional gig in return for facilitating the transaction and acting as an escrow service or middleman. It's not so different from television ads now, just a broader market with lots more content producers that have large fanbases across demographics TV just doesn't have.
