It sounds nifty and I'd love to use it -- but on the off chance that you might use it to run my passwd file, I don't think I'll contribute any CPU time...
Think carefully - if they can use it to run your passwd file, then you're already screwed. How did they get your shadow passwords? :) Remember - you can't mount a dictionary attack unless you have an oracle of some sort to tell you if each guess is right or wrong - whether that be a known-correct hash of the password, a service that provides non-rate-limited authentication attempts, or other methods (such as being able to recognize plaintext because it's within the unicity distance - http://www.schneier.com/crypto-gram-9812.html#plaintext)
