Correct me if I'm wrong, but it looks to me like the two existing versions are technically identical - the difference is how they derive the key used to encrypt the document. (The account-based option gets the key from Adobe's server based on the account ID, while the password-based option is a function of name/password - in B&N's case, credit card number.)
