It's very hard to come up with a workable way to do a true read-only
mount of a journaled filesystem such as ext3 - what do you do if there's
anything in the journal that needs to be replayed?

Your best bet is to not worry about the filesystem, and look at flagging the
underlying block device as read-only.
