I do not agree with you. That's something different. The last point is
about someone sniffing the traffic and getting your private keys (i.e.
by force) and still not being able to decode anything. Logging is about
the guy you're talking to. There is no _software_ that can tell you if
you can trust him. You have to trust him, that he's not logging. You
have to trust him that he keeps his computer free of spy ware, etc.
Logging affects only the third statement anyway. And not even that,
because you can always say the he edited the log with a editor.
This stuff is all about "the others" not about the guy you're talking to.
At least if I got it right. ;-)
