Well, it would probably be an interesting experience... not that I would care to find out. That's why I said the killer application would probably not look like money to us.
Take Youtube, for instance: people go to considerable lengths to create videos that others find interesting. Then they sit glued to the screen watching the view counter go up. There's a currency: people paying with their time (which everybody only has a fixed amount of) for someone's work creating videos.
Now have some ISP give extra bandwidth to people with Youtube videos over x thousand views. It doesn't cost them much "real" money since bandwidth is more or less a fixed cost but you have turned "virtual" money into a currency.
Granted, the example is a bit contrived but you can see where I'm going with this.
