It's not imposed by TeX or OS X, but I believe it is based on TeXLive

Possibly, but what if you have your TeX software installed on a  
filesystem that is also shared with Linux/x86, Solaris, Windows,  
etc., etc.? This setup was designed with more than just OS X in mind.

To quote from http://developer.apple.com/wwdc2005 ....
"Note that with the exception of the WWDC 2005 Keynote, all  
information presented or provided to you by Apple during WWDC 2005,  
including the information on the Attendee Site, is considered  
Confidential Information and is subject to the terms and conditions  
of your ADC Membership Agreement with Apple."

I imagine that all who buy one, being Select or Premier ADC members,  
will have already entered into some kind of confidentiality  
agreement, and the fine print will say that the Transition Kit is  
covered by this. But I haven't looked to see exactly what it says.
