If it is convergent encryption, though, a rights holder can still check if their content is being uploaded and send out takedown notices and then it's Rapidshare all over again. Not saying that it's the users/market Mega crowd is going after.

Since the same plaintext produces the same ciphertext with different passwords dosn't it expand the search space for a possible attacker?
