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.

Cheers

Don
