I have also read references in MacWeek and MacOSRumors and such that the G4 processors will be capable of symetric multiprocessing (sp?), and that the design of the chip will make for a very low overhead penalty in processor to processor communication, which is what reduces the benefit from a straight multiple factor.
In the other part of the equation, the Operating System, OS X will definitely support symetric multiprocessing. My understanding is that since OS X is based on Unix, unlike Window NT which is not, OS X will be more efficient at allocating processing power and will do it much more reliably.
Any application will benefit from this type of set-up, since the OS takes on the duties of apportioning processor duties. I believe the "SawTooth" motherboard design, which will supplant the new 'blue and white' G3's later this year, will be the first to sport the G4's. Since they will ship with OS X, all the pieces should be in place for processing power to really take off on the Mac. (I can't wait)
