Yeah, I think Convergent did the STREAMS packaging, then Lachman bought
the stack, I ported it twice (ETA & SCO), then I believe it was Bill
Coleman (not positive on the name, it was the VP of networking) at Sun
that bought rights to the stack from Lachman under pretty unfavorable
terms, then Sun got unhappy with the terms (and the performance),
contracted with Mentat to do a new stack and I think that stack is what
remains in Solaris.
