	Have you ever thought that things can be done, because you have the source code 
and it's modular and documented (commented)?

	It's interesting how people not in the know have hard opinions on what's 
possible and what's not.

	BTW, do you know more about it than Apple itself?  Have you read the URLs I 
gave you?  If that doesn't make up your mind, I can only suggest you download 
and read the code.

	You're young.  You do not remember how fast NeXT started from the blink in 
Steve Job's eyes.  No time to create a kernerl.

	Funny also how you talk about ruining userland.  Even BSD itself wasn't ruined, 
just that they added bloat in the form of Mach.  As for the user experience, 
they have their own filesystem hierarchy and stuff.  I would hardly call that 
ruining.

	You forget only FreeBSD is i386 specific.  BSD itself wasn't even created on 
the i386, and NetBSD has porting in the center of its focus since starting. 
AFAIR BSD started on DEC PDP series machines.

	BTW, even by virtue of being far smaller and more mature BSD is easier to port.
