I don't think the Unix versions were independent, just MIT X11 + whatever "value-added" the vendor wanted to add (often some proprietary desktop environment). DEC by the way added X11 to VAX/VMS and called it DECWindows, but it was still MIT X11 underneath.(DEC was also one of the major contributors to early X11). I actually at one time ran a remote DECWindows terminal window from a Unix workstation when I needed a session at the VAX, but that was a bit rude way of doing it, because of larger resource usage compared to a telnet session. So being a terminally nice guy I stopped doing it when I realised this.
