Subject: Is there a way to trace back Tor user

Regarding to recent debate about the use of Tor. Just wondering if it is
practical to trace back the user if he is using Tor to hide his origin. As
far as I know, there were several approaches using timing correlation to
trace back TCP connections. It seems that the technique is there but the
problem is the placement of monitors. Since the Tor servers are scatter
around the world and it is impractical to access  them all.  If in a perfect
world that you can monitor all the traffic of all Tor servers, you should be
able to trace back with high success rate.

Is there any better solutions? Thanks.

yours,
Michael
