Maybe a brain wallet or something... Someone used to run a website where there were 10BTC and 20BTC challenges to guess the passwords, but I think the site is offline now. This might lead to something similar.  I think i'm moving on from this hunt for now, I can't seem to find any more clues to get to the next step.
