The Network stack they did publish would be available, but what > about the AT&T version? I can't speak to the legal stuff but Solaris shipped with Convergent/Lachman's TCP/IP stack. Briefly if at all. Then Mentat was contracted to do a higher performance TCP/IP which was a bloody mess if I recall correctly. Full of "fast paths" that worked around the STREAMS shortcomings. Sun would have been far far better off doing what you did at Stellar.
