Sounds interesting. Currently max main memory for a PowerBook G3 is 512 MB RAM (!).
This is large enough to reduce disk access access quite a lot compared to 8 MW RAM
MacIvories -> speed up. Next years PowerBooks sure will use something
like a 500 Mhz G4. Since MacOS won't do 64 bits soon, you'd be limited to 32 bits.
Assuming that the emulator would run as a Mac application. The new CARBON
approach of the upcoming MacOS X client would make things more stable
and multiprocessing on desktop machines a viable option.
