I've been thinking a lot about this, but the problem you run up against is that it's difficult to distinguish real economic activity from one person shuffling money around, and similarly, it's easy to hide activity by keeping a private ledger. That said, it's possible the inertia of the real market would stop anyone manipulating inflation in this way. I'd really like to see an experiment on these lines.
