the MacBook Pro's version of OSx86, in /System/Library/Extensions lies a little message in a kernel extension for
<string>Dont Steal Mac OS X

Given this message, I have a hunch that perhaps Steve has encouraged his team to implement other forms of copy protection into the production copies of OSx86, perhaps in the form of watermarking. Also, I haven't seen any mention of this in the Intel iMac's version of OSx86. Feel free to pontificate in the comments. Is this a warning that perhaps there are stronger measures coming to find users running OSx86 on non-Apple hardware?
