There's already a historical basis to believe Marlowe may have written the works of Shakespeare. And the number connections are pretty strong, if a bit of a stretch. Doubly (perhaps triply in this case, considering the encrytpions of his name used to encrypt the numbers in the acrostic) encrypted messages are much harder to prove than singly encrypted messages. At any rate, I feel there's good reason to believe Marlowe wrote the plays, in the same way that a woman probably wrote Homer's Iliad and Odyssey.
