Remotely identifying computers via clock skew

ZDNet Australia is reporting that a University of California doctoral student has developed a technique for telling different computers apart over the network by detecting their clock skew. According to this article, the technique works behind NAT devices and over long periods of time, even if devices move around a lot.

I need to read the research paper in order to decide whether I believe this or not, but it sounds plausible. Unfortunately, the paper is not yet available.

UPDATE [2005-03-04 12:42]: The paper is indeed available, and can be found here.
