To use my TrueType/DirectWrite analogy, "implements a CDM" would be like "implements *some* font format" while the analog for "implements TrueType" would be "implements the PlayReady protocol with keys whose certification chains to the PlayReady root of trust". I don't see OS X and Ubuntu (or old older versions of Windows or other Linux distros) implementing the PlayReady protocol with keys whose certification chains to the PlayReady root of trust and, more to the point, I don't expect to see a Free Software implementation of the PlayReady protocol with keys whose certification chains to the PlayReady root of trust, so I don't expect an analog of what FreeType is to DirectWrite to come to existence for Windows 8.1 PlayReady, so I don't think it's worthwhile to speculate about your "if" scenario. My point was that its incorrect to suggest that the Windows system services Firefox currently uses would be analogous to Windows 8.1 system PlayReady, since the services currently used to implement Web-exposed features have Free Software substitutes on Free Software systems (even if possibly with differing performance characteristics). -- Henri Sivonen hsivonen@hsivonen.fi http://hsivonen.iki.fi/
