HOOKING UP 3 Apple G4's

Hello All

I am not a programmer/whizz, but I would like to know if/how its possible to connect 3 Apple G4's into one system, using OSC of course, and not MIDI.

I am running Pro Tools, and Reason on the one, with a few virtual synths, and Cubase and Reaktor on another, and I would like to use the third to do a bit of DSP/number crunching on the side.

Excuse my ignorance but this to me is the holy grail of music making today, as was sampling 15 years ago..

Any input highly appreciated.
