It was second hand and unverified information, as I said. Perhaps I even 
misheard them and they did, in fact, say Ultrix. Let me backpedal and say 
"I heard one or more of the VMS TCP/IP stacks came from a UNIX variant". I 
don't know much about VMS, as I said. I wasn't trying to be an expert or 
ruffle anyone's feathers, that's why I added the qualifiers.

Well, for all I know, they wrote it from scratch. All I'm saying is that 
the presence of multiple IP stacks looks to me to be unwieldy, organic, 
and incremental. DECnet might be totally integrated and awesome, but it's 
also proprietary, seldom used, and seems to mean different things to 
different people since it was developed in "phases" which bear only loose 
resemblance to each other in form & function.
