Not a new idea, although I don't know where I heard it the first time.

Probably off-topic for this list, but this doesn't make much sense to me, as
such non-logging implementations likely will be just as illegal as notifying
the client of the change, which seems an overall better solution if you are
willing to break the law (provided you can hide the notification from
authorities).  [In Germany, means of surveillance are required by law, as is
record keeping].

Getting back on topic, cryptographically speaking, it's also quite possible to
just monitor all ingoing and outcoming traffic and correlate one with the
other.  Preventing this is not easy, even if encryption is used.

Maybe, and this would be a major confirmation that TPM actually works at any
non-trivial scale.  I can't see it, though.
