Pretty much precisely as predicted, there's a new Trojan out that exploits Sony DRM copy protection vulnerability. Details are sketchy at this point - it appears to have been spammed out from a hijacked machine as an email. The best info I've found so far has been Sophos' press release. They have a tool to detect and disable Sony's cloak.

Update: According to Brian Krebs' Security Fix column, a lawsuit has already been filed in California charging Sony with violation of three state-level statutes, and another state-oriented suit will be filed in New York this week.

Update 2: A press release from Electronic Frontiers Italy (which I take to be an Italian EFF-alike) describes a formal request made by that organization to the Italian "Commander in Chief of the Fraud Contrast Group of the Financial Police" in an effort to identify for legal purposes the authors of the malware, whether anyone else is doing similar things, and have them prosecuted under Italian laws that forbid "damaging" personal computer systems. The particular law(s) that apply to this situation aren't spelled out in the ALCEI release, but perhaps that's something the police are expected to determine.
