:It is, unfortunately, beyond the scope of this project to make our 
:implementation of Unix compatible on a binary level with Linux. However, 
:one of the keys to the success of Unix in general is its high level of 
:source-code compatibility, and we plan to make this implementation as 
:close as possible to a Linux implementation from a source-code 
:standpoint so that source code that compiles on one platform will 
:compile on the other platform without any modification. 

I think what they are trying to say is that it is impossible, but that 
the source is compatable, thus allowing compiliation on the PMac 
platform.  What exactly does a not disclosure agreement limit a person 
to?  Also I think that if you wan't to find out more you might want to 
follow the thread on comp.sys.powerpc or comp.os.linux.*.  What would 
happen if the NetBSD_Mac team would sign a now disclosure agreement.  I 
assume that there are valid reasons for not doing it, but curiosity just 
overwhelms me.
