Okay.  Fair enough.

I don't think the people using "Open Systems" as in Mainframe vs Open 
Systems vs Wintel were differentiating between "open" vs
"distributed".

  For example, I'm not sure anyone would call VMS an
open system, yet 
 clearly it's distributed (VAXcluster). 
What is "open" in this context?  Is it open source?  Is it open 
communications protocols?  (As in OSI / POSIX.)  Is it something else?

I suspect that OpenVMS qualifies as the OSI / POSIX meaning of "open". 
;-)  But OpenVMS is decidedly not open source.

OpenMVS (a.k.a. USS) on the mainframe comes to mind too.  }:)
