IMHO the anonymous CryptoNote creator/author "Nicolas van Saberhagen" may very well himself BE Satoshi (S.N. / N.S.) as Satoshi "disappeared" to go and "work on other things" just around the time CryptoNote appeared on the scene, I believe.
Yeah I have always subscribed to this theory. I guess we will never know for sure.
And how exciting would it be if that were somehow to be confirmed? Now that would definitely be a LUNAR moment!
