There is a mention on the MacInTouch web page about a discussion with Apple's
Avie Tevanian about the future of Mac networking.

     "The bottom line is that Apple is firmly committed to the BSD
     architecture for Mac OS X, using Apple-enhanced NetBSD source code
     (thus avoiding dependency on any third party)."

Cool!  (http://www.macintouch.com/ if you want to see for yourself.)
