Ah I see this was in reference to your convergent encryption post above. Point taken.
Assuming that it works this way, it would allow Mega to figure out if you own a known "bad" file. Just take something like "New_Jay-Z_Album.zip," hash it, and try the hash against your encrypted files. It seems like Kim is trying to avoid this problem.
