(Re: jaekwon) Yes, I think you're right.
Even if the encryption speed gain is small---it should make Scramble better for anyone who's on a slow connection, since they'll only have to send about 1/n times as much data to send and email with n recipients.
This seems esp important for group discussions where people use Reply All.

On the server end, the message content could either be stored uniquely or once per user. The former would save disk space, but this might make user account management more taxing, e.g. deleting or migrating whole accounts."
