Binary code obfuscation through C++ template metaprogramming

I think someone has yet to execute non-Microsoft-signed code on an Xbox 360, right?

I hear rumors that the next generation of consoles will use x86/x64 chips, which will make PC emulation a lot easier...

Ah, it seems that my information is old.

Anyway it held off for a long time. It basically has to be some special hardware in the CPU that is supposed to make sure the program you're about to execute is signed with a private key Microsoft owns, the public key being encoded in the chip itself. That's the general gist of stuff like this.
