I'm having a hard time understanding how NaCl improves or alters this at all. I understand NaCl is a way to execute x86 binary code inside a Web browser. I also understand NaCl is not enabled by default. I can't see anything anywhere on this page that eg fires up DOSBox. I also can't see anything giving me errors saying "NaCl is not enabled!"; I'm running the stable build, which doesn't enable it, and I've had no reason to change that. This looks like yet another reimplementation of a "web-based desktop".
