This is fine if you have a router or switch that supports Gigabit ethernet but if you don't and are unwilling to splash out on a expensive new router or ethernet switch hub just for Logic Node, then here's a simple, fast and cheap way of connecting two Macs. Apple states that you need at least a PPC G5 mac with Gigabit ethernet connections.
Use a crossover cable - the best approach is to use an existing ethernet cable and an adapter for gigabit connection. This is more flexible in the long run as you can change the cable attached at a later date if you need a longer or shorter length if equipment is re-positioned.
I found the Hama Cat 5 Crossover adapter works fine (link below) is well made and great value.
So try out Logic Node simply, and cheaply! (More notes are in the comments)
Logic 9.1 64bit update - Logic Node is not yet supported when running in 64 bit mode. (Jan 2010)
