These types of systems work well on newer consoles, they don't totally stop piracy but they make it enough of a pain that only the most hardcore will even try, which is basically a good enough solution because most of those people will not buy your game in any case. BUT, this is something you can't really retrofit on to an existing platform (especially one with tons of different hardware vendors) like the PC. It only makes sense to use this system if you're willing to tell every potential customer who has a motherboard without this chip that they can't play your game. Even if all new PCs magically started including them tomorrow (which won't, of course, happen), it would be years before any developer locked their software to this system. A lot of indie developers are paranoid about supporting DX7 level 3D hardware, and that's been around for almost a decade, how long would it take until you could realistically start using this protection system? I'll probably be dead before then. So ultimately this has a huge chicken and egg problem, developers (including commercial) won't support it unless the installed numbers are huge and there isn't much incentive to buy a motherboard with this built in unless there is a substantial software library that requires it. If Microsoft didn't have the clout to make Palladium happen, what chance do these folks have? Absolutely none.
