As long as 'someone else' controls the medium thru which the messages pass,
traffic analysis will be possible.  It may be a large problem, but it will
still be doable with sufficient motivation.  When you have an untappable wire
between the sender and recipient, then traffic analysis is impossible (and
crypto unnecessary).  In order to get to the remailer chain you mention, I
(for instance) can ONLY pass thru a couple a machines, which if properly
monitored, reveal the traffic flow despite the remailers.  You can still beat
traffic analysis (and you still need crypto), but not in this medium.
