If Paul Le Roux is really Satoshi, then Satoshi's wallet is in the hands of the CIA, and they probably already have the password, which could be obtained through torture.
An interesting realization I had is the fact that TrueCrypt FDE is only available through Windows even to this day in it's VeraCrypt form. By looking at the Bitcoin codebase you can tell satoshi was a so called "windows guy", he was compiling .exe only and Linux came way later. Paul used TrueCrypt and not dm-crypt, LUKS or any of the other Linux alternatives. So there is another connection. The list of coincidences I have is pretty good. Nobody is saying Paul is satoshi, it's just another decent contender in my book.
As far as bruteforcing, cascaded ciphers were added in 2004 so the encryption used by Paul probably has a combo of AES-Twofish-Serpent or something along the lines with AES-256 and a strong password which means I don't believe 10 years of bruteforcing is going to be enough (assuming CSW's farm is legit and has been working on it for 10 years which I doubt).
