Logic Pro 8 multiple computers


I've been a Logic user, in one form or other, since 1990. Wouldn't switch for anything. My question: can someone explain or lead me to a link that details the advantages, or dis-advantages, of linking two iMac's. I have a 2.4 Intel Core 2 duo with 4 GB Ram and am planing on upgrading, but have a somewhat restrictive budget. Would love to purchase a Mac Pro 8 Core, but not possible at this moment. Tho I could afford the new iMac i7 plus some Quantum Leap Orchestra software and link the two computers. I'm using Logic 9.

Any suggestions would be greatly appreciated. BTW, I still have my old Atari ST with C-Lab Creator software. Don't use it but can't part with it either.

Thanx much, Tony
