Well, I’m using the term “debate” loosely here because it seems to me, given the marshalled evidence, there isn’t much of a debate to be had, but in any case, Microsoft has responded to Peter Gutmann‘s cost analysis of the DRM subsystems in Windows Vista (of which I’d written about earlier), and also in system hardware that has anything to do with handling of so-called “premium content” (i.e. content encoded onto newly emerging HD-DVD and Blu-Ray discs). Their reply is here..

Peter Gutmann’s rebuttal to Microsoft’s response is here..

..which is an appendix of his overall “Cost Analysis of Windows Vista Content Protection” paper.

If you are at all curious as to the veracity and logic of Microsoft’s response, it is worth reading Peter Gutmann’s response in detail.
