"For some there is no burden of proof high enough, no evidence that cannot be dismissed as fabrication or manipulation... You should be sceptical. You should question. I would. I will present what I believe to be 'extraordinary proof' and ask only that it be independently verified. Ultimately, I can do no more than that."
Um, no CW, all you have to do is sign a message with a private key known to be owned by Satoshi (take your pick, there are several). This doesn't require in-person meetings. It doesn't require special clean laptops purchased down the street. It doesn't require clean flash drives, SSL connections, or tarot readings. Just sign a simple message and be done with it. Here's a thought - sign the top headline from yesterday's NY Times.
Verifiable proof is not difficult to design. It is not difficult to verify. It is not difficult to create, unless of course you are not Satoshi and do not have access to any of his private keys.
