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.
