[LAU] all in ram?

Any info would be appreciated. It would certainly help me to make, what i
hope, is better decisions.

For further thought, i'm considering lashing the two boxes together with
twin Gigabit Ethernet cards in each, to maximise throughput.

The initial intention for consideration is 64GB ram in the Sampler box (to
run a big orchestral template entirely 'live'), and 32GB in the DAW box.

A further question arises from this concerning Netjack.

Can i use multiple in/outs with netjack? Or is the connection single audio
midi in/out only?
Or can i simply use GB ethernet to stream audio midi directly to/from LS
in/out, and use just Jack on the daw box to handle any ports/clients?
