An amazing blow-by-blow log of a software company going after an infringer (via Slashdot).
A couple of my initial reactions to this story:
1.  This is why IP lawyers need to be forensic scientists;
2.  This is why IP lawyers go after ‘middlemen’ such as ISPs;
3.  This is why anonymity on the ‘selling’ side is against public policy.  The way to resolve the privacy vs. consumer debate in arenas such as whois is to create commercial zones on the Web.  If you want to sell, do so from a ‘.cert” and say who you are.
