I think your objections to using SSL are something I'm finding difficult to
understand. You don't like it that SSL cuts off man-in-the-middles?
SSL doesn't prevent a proxy, by the way, it simply requires that one is
configured explicitly instead of being implicit.

I'm also confused that you're advocating both keeping no state and keeping
state (e.g. cookies) at the same time?
