Almost... before starting jack, maybe before plugging in the the 
ultralite's USB even, connect the ndac. Then, using the web app on the 
ultralite... uh, oh... Hmmm I guess that means you already need an AVB 
type switch :) but anyway, using the web app, set up the ultralite to 
accept the 8channel stream from the ndac which will make the utralite have 
more or show more inputs. Now connect the ultralite to the computer and 
the extra channels shoulld show.

Now I am not sure this is exactly right. The ultralite may show enough 
channels all the time (there is a limit BTW). However, from reading the 
manual, I get the idea that routing still must be performed and that ALSA 
(via USB) can't do that. You need to use the web interface which uses the 
same network port as the AVB network. So a minimal system is an ultralite 
only works as audio interface and the network needs to be connected to 
your computer. The next step to add one AVB endpoint requires an AVB hub 
as well. So that would be three boxes for a minimal remote box system. In 
my case, though I would love to experiment, it will remain on my todo list 
for a long time yet :)  My legacy PCI interface will have to do.
