I'm skeptical. As far as i can tell their 'unhackable' solution is some form of super advanced ASLR that moves 'some' kind of software around and decrypts and re-encrypts it on the fly. By continually encrypting with new keys and such they are betting that an attacker won't have the time to find vulnerabilities. However, this all assumes the 'advanced ASLR' itself isn't vulnerable, and moreover they are not building software that has no bugs, but rather just throwing all the bugs behind a pretty big locked door.

Sure it's a cool idea, but lets not call it unhackable.
