I wonder if this is a problem that could be solved with an evolution of the technology. Meaning bitcoin (or a future crypto-currency) policing itself in a distributed manner, without requiring a central authority. Perhaps some way to hold referendums as to whether specific coins should be considered stolen. And if passed, some predetermined resolution mechanism would come into play, whereby the stolen coins would no longer be valid anywhere, and new coins would become available - either returned to the theft victim, or added to the mining pool, or something.
