GPO is choking my system.(dual 1.25 with 2 gig RAM and a Digi 002r running Pro Tools 6.9. GPO as an RTAS Plug)

I need more voices.

I also a 1.5 GHZ Powerbook with 2 gig of RAM and an M-Box.

Both have GPO installed. Can anyone give me an idea of how to connect them so that I can use the processing power of my Powerbook with my Main Daw to get me more voices?

What kind of cable? How to set-up Midi (over lan?)

Any input would be appreciated.
