Some people have suggested that this is a good application for

doing timing attacks directly against a proxy you operate, from

the same network, is probably pretty effective!
You've lost me here - could you explain further? How would it
prevent logging
data?
It's exactly right though! This has got to be the only good use of
Trusted Computing I've ever seen!
Basically you know, and I know, precisely what's running on the
machine. Say we share the secret keys of the tor nodes, they'd be
guaranteed to be running a known, non-logging version of Tor!
This approach might
be more relevant to lower-latency anonymity services such as e-mail
remailers.
