Huh? The advertised reason for putting in all this stuff was to provide
a thought-through, secure mechanism for dealing with connection
information. If we haven't done that thinking yet, I'm of the opinion
the whole thing should be ripped out until we have. It's of exactly
zero value if it cannot be trusted with a password.
