Its been a while, but I just read an article arguing the case that Len Sassaman was a Satoshi. It was a neat article, so I watched one of Len's Defcon talks about remailers from waaay back in the day.

In his talk, Len mentioned that most remailer security analysis assumes homogeneous Poisson email arrivals. He pointed out how bad an assumption that is for email.

I still think it was a solid assumption in the Bitcoin white paper.
