In which case you're in luck - Native Client is completely open, both the source code and the executable format[1]. However, it's new and hasn't been submitted to the standardization bodies yet. With that in mind, I have a real hard time getting worked up over Google putting a draft feature they're working on in their own browser. I suppose if Mozilla and Microsoft really want to implement a moving target, there's nothing stopping them from doing so. If Chrome doesn't restrict it, then they start getting negative press about how this new thing they created doesn't work.
