Now try Satoshi Nakamoto with bitcointalk posts and papers in cryptography.
I have a suite of nyms I created over Tor, and exclusively use via Tor, which I use to discuss certain topics.
It's hard to do a stylometric analysis when you don't have anything to compare to. Professional writing is very different from informal conversation.
If someone doesn't have a Facebook, gmail, twitter, etc it would be very difficult to find that person through stylometric analysis IMHO.

Another interesting analysis would be to compare the structure of code between the early bitcoin code and code written by likely suspects. Perhaps variable naming convention will identify Satoshi.
I agree. My bet is at least two: one theory heavy "ideas guy" and one more software engineering oriented programmer who did the heavy lifting on implementation.
And I have also noticed that these types of analysis are for single authored documents.
I suspect it will stay a secret for a long time... maybe we'll get some deathbed confessions in a few decades.
