ZfcUser won't support the old MD5 hashes used by RS (and we wouldn't want to change that). We could force everyone to recover passwords, but it would be nice to be able to authenticate than upgrade older passwords.
We really don't really want to send the MD5 every time
Perhaps we can identify ZfcUser passwords by a prefix and redirect others to an upgrade screen that sends the MD5 version for confirmation and upgrade purposes.
