This is way more than useless. Cmon, if it will be more than 8 charc. , 2.2 btc won't recover the money spent on resources. I know 1 or 2 russian companies that will ask you to pay them per day with already made software for finding the passwords, just enter your wallet.dat. But if it takes 1 day, or 1 week or 1 year until it is done that's a different story.

Anyway, still... quite useless.
