I never claimed that Rosetta has anything to do with Classic. I even asked "what about it?".
The "what" is that there's a proven technology (QuickTransit by Transitive) which eliminates the need for porting to the x86 architecture.
Apple could have done the work (probably significant) to get Classic or an OS9 "Wine-like" environment running under QuickTransit (aka "Rosetta").
So, the move to Intel was a convenient excuse for Apple to use to kill Classic, but it would have been possible to keep it around.
It would be nice if VMWare could support early Mac OSs to run.
VMware does not do instruction set (ISA) emulation, the virtual machines run with the native instruction set.
QEMU (http://fabrice.bellard.free.fr/qemu/status.html) does ISA emulation, and already can run on Mac OSX Intel. That would be another option.
