Pay a Reward to Catch a Hacker?

When I read an article titled "Sony Considers Offering Reward To Help Catch Hackers" it demonstated a new approach to catching hackers. Traditional methods to catch real world criminals have used cash rewards for information and leads. I am not sure how effective it would be in tracing cybercrime and would be keen to know the results if indeed a reward is offered. I have found that cybercriminals who hack for profit are more difficult to trace then those involved in cyber protest or hack for fun.
