It would be interesting if you could create a "pool" of people's machines to crack (err... recover) wallets, and distribute the fee to them based on how much work they did. I imagine you could do something similar to mining pools.
or similar to vanitygen-pool. cool idea.
I'm not sure its feasable. You'd have to find a way to divide up the search space and somehow make provable some subspace has been searched. This is different from vanitygen or mining where there are many solutions, not just one.
Yes, I've thought a bit about doing this (splitting up the search space and making a public API to access it).
Perhaps in the future.
However, for now, I can just run up multiple amazon instances to do the same thing.
p.s. In response to demand, I now have added the ability to walletrecoveryservices.com to brute force crack the blockchain.info wallet format too. If you have a wallet.aes.json file backup (for your mobile or online account), then I can help you recover your password if you've forgotten it.
