netjack over localhost does not make sense. you can just use jackd on

your primary soundcard and alsa_[in|out] on your secondary. but the

realtime resampling will either chew up insane amounts of cpu, or

degrade the sound, or both. ok for telephony or for listening to

unimportant stuff over small speakers, but not for serious work.
generally, multiple soundcards make sense in three scenarios:

a) you have professional soundcards that can sync to an external source

(sometimes, that could even be spdif), in which case you can use an alsa

multi device without sound degradation.

b) you want to fiddle (possibly including soldering the oscillator

output of one card to the clock in of the next...)

c) you really don't care about the sound quality of the secondary card.
if you want to get real work done, shop for a single multichannel card

instead.
