Microsoft has announced a system that would enable a CD to play normally on both a PC and a CD player yet still allow music providers to control copying, according to a Reuters report from the Midem music industry exhibition now on in Cannes. The Windows Media Data Session Toolkit "was co-developed with technology partners Phoenix-based SunnComm Technologies and France's MPO International Group", it says. Presumably this is a Microsoft Toolkit for the SunnComm copy-control system known as MediaMax CD-3 Technology, launched last October. Update: Yahoo now has a NewsFactor story with more detail.
