Back in the day it was hard to predict what was going to work. Commercial Unix versions were still very competetive, and the legal case AT&T had brought against BSD had not played out yet. Free alternatives were few, and who could have predicted that Linux would emerge as the winner? It could have been MACH, although its BSD-derived userland/system binaries were as problematic as BSD itself at the time.
Correct me if I'm wrong, but I think this never shipped as part of Amiga Unix, only as part of a third party graphics solution (DMI resolver?).
That's all I've been able to dig up too ... Was with the DMI Resolver for some reason. Shame, as even Atari SVR4 has Motif, which gives them NCSA Mosaic. Still, that requires an Atari TT and that's pretty damn rare compared to the A3000.
I agree that around 92 it was still very hard to tell what was going to win even 5 years later, but the time spent by the GNU people by then, with very little to show for it, on HURD was a good sign that Mach wasn't going to take over, especially as the it's disadvantages by then (speed between servers, etc) were well known. And hardware was moving or had moved to RISC for all the major players in the UNIX world.
