I personally think Hyperion would have a better chance if they ported OS 4.1 to x86/x64.
Let's face it, Intel hardware is more readily available and would most likely open up a huge user base.
It would also enable developers to make write software for OS 4.1 with minimal outlay. If it ran in Vmware, even better!
Imagine where Linux would be if it could only be run on PPC or some other obscure hardware platform - nobody would bother.
