Logic Node And Connections, Logic Node and connections Options

[polive]

Hi, I have a PowerBook G4 with built in 10/100 ethernet. Only USB1.1.
I'd like to use Logic Node: I have an audio interface in my firewire 400 port (only 1 firewire port) but can daisy cahin from it - does anyone know how well that would work with Logic Node?
What about if I bought an Airport Extreme setup - would that allow me a fast enough connection to a G5, or any other Mac?
Any help on whether I can make my PowerBook use Logic Node much apprecitated!
