Not unrealistic at all, but I'd be nervous about implementing it if I were
a big enough targe.. er, large company.

Unlikely, unless Apple decides to be a systems house like MIPS or somebody.

A 680X0 machine can run all other 680X0 software, simultaneously if you like.
(It helps to have an MMU to catch addresses to memory locations which 
activate special features on the machine(s) being 'emulated.')  This capability
is more powerful than the 8088 capability that 80386 machines have, but
I've never heard of anyone except Motorola using it (on the 68k).
Imagine being able to run Mach/Unix, Mac, AND Amiga software on your NeXT 
machine.

Of course, performance and licensing are different issues.
