I am not sure I got the whole sentence, but should we not already assume
that "hashed passwords" can be attacked quite successfully using current
hardware, such as GPUs, maybe multiplied in a botnet. My working assumption
is that "if a human can remember the password, a computer can retrieve it
from the hash!" Not sure that we need mining hardware for that...
